Django: Arbitrary number of unnamed urls.py parameters | 249,110 | <p>I have a Django model with a large number of fields and 20000+ table rows. To facilitate human readable URLs and the ability to break down the large list into arbitrary sublists, I would like to have a URL that looks like this:</p>
<pre><code>/browse/<name1>/<value1>/<name2>/<value2>/ .... etc ....
</code></pre>
<p>where 'name' maps to a model attribute and 'value' is the search criteria for that attribute. Each "name" will be treated like a category to return subsets of the model instances where the categories match.</p>
<p>Now, this could be handled with GET parameters, but I prefer more readable URLs for both the user's sake and the search engines. These URLs subsets will be embedded on each page that displays this model, so it seems worth the effort to make pretty URLs.</p>
<p>Ideally each name/value pair will be passed to the view function as a parameter named <code>name1</code>, <code>name2</code>, etc. However, I don't believe it's possible to defined named patterns via a regex's matched text. Am I wrong there?</p>
<p>So, it seems I need to do something like this:</p>
<pre><code>urlpatterns = patterns('',
url(r'^browse/(?:([\w]+)/([\w]+)/)+$', 'app.views.view', name="model_browse"),
)
</code></pre>
<p>It seems this should match any sets of two name/value pairs. While it matches it successfully, it only passes the last name/value pair as parameters to the view function. My guess is that each match is overwriting the previous match. Under the guess that the containing (?:...)+ is causing it, I tried a simple repeating pattern instead:</p>
<pre><code>urlpatterns = patterns('',
url(r'^browse/([\w]+/)+$', 'app.views.view', name="model_browse"),
)
</code></pre>
<p>... and got the same problem, but this time <code>*args</code> only includes the last matched pattern.</p>
<p>Is this a limitation of Django's url dispatcher, and/or Python's regex support? It seems either of these methods should work. Is there a way to achieve this without hardcoding each possible model attribute in the URL as an optional (.*) pattern?</p>
| 16 | 2008-10-30T02:18:32Z | 255,251 | <p>Same answer came to me while reading the question.</p>
<p>I believe model_browse view is the best way to sort the query parameters and use it as a generic router.</p>

| 16 | 2008-10-30T02:18:32Z | 19,378,600 | <p>I think the answer of Adam is more generic than my solution, but if you like to use a fixed number of arguments in the url, you could also do something like this:</p>
<p>The following example shows how to get all sales of a day for a location by entering the name of the <code>store</code> and the <code>year</code>, <code>month</code> and <code>day</code>.</p>
<p><strong>urls.py</strong>:</p>
<pre><code>urlpatterns = patterns('',
url(r'^baseurl/location/(?P<store>.+)/sales/(?P<year>[0-9][0-9][0-9][0-9])-(?P<month>[0-9][0-9])-(?P<day>[0-9][0-9])/$', views.DailySalesAtLocationListAPIView.as_view(), name='daily-sales-at-location'),
)
</code></pre>
<p>Alternativly, you could also use the id of the store by changing <code>(?P<store>.+)</code> to <code>(?P<store>[0-9]+)</code>. Note that <code>location</code> and <code>sales</code> are no keywords, they just improve readability of the url.</p>
<p><strong>views.py</strong></p>
<pre><code>class DailySalesAtLocationListAPIView(generics.ListAPIView):
def get(self, request, store, year, month, day):
# here you can start using the values from the url
print store
print year
print month
print date
# now start filtering your model
</code></pre>
<p>Hope it helps anybody!</p>
<p>Best regards,</p>

| 16 | 2008-10-30T02:18:32Z | 35,575,143 | <p>I've an alternative solution, which isn't quite different from the previous but it's more refined:</p>
<p><code>url(r'^my_app/(((list\/)((\w{1,})\/(\w{1,})\/(\w{1,3})\/){1,10})+)$'</code></p>
<p>I've used <a href="https://docs.djangoproject.com/en/1.9/topics/http/urls/#example" rel="nofollow">unnamed url parameters</a> and a repetitive regexp. Not to get the "is not a valid regular expression: multiple repeat" i place a word at the beginning of the list.</p>
<p>I'm still working at the view receiving the list. But i think ill' go through the args or kwargs.. Cannot still say it exactly.</p>
<p>My 2 cents</p>

Virtualenv on Ubuntu with no site-packages | 249,283 | <p>I've been using virtualenv lately while developing in python. I like the idea of a segregated development environment using the --no-site-packages option, but doing this while developing a PyGTK app can be a bit tricky. The PyGTK modules are installed on Ubuntu by default, and I would like to make a virtualenv (with --no-site-packages) aware of specific modules that are located elsewhere on the system.</p>
<p>What's the best way to do this? Or should I just suck it up and drop the --no-site-packages option?</p>
| 24 | 2008-10-30T04:32:52Z | 249,342 | <p>One way is to add the paths to your code using sys.path.</p>
<pre><code>import sys
sys.path.append(somepath)
</code></pre>
<p>Another way is to use site, which processes .pth files in addition to adding to sys.path.</p>
<pre><code>import site
site.addsitedir(sitedir, known_paths=None)
</code></pre>
<p><a href="https://docs.python.org/library/site.html" rel="nofollow">https://docs.python.org/library/site.html</a></p>
<p>But you probably don't want to add this to all your related code. </p>
<p>I've seen mention of sitecustomize.py being used to perform something like this, but after some testing I couldn't get it to work as might be expected. </p>
<p>Here it mentions that auto-import of sitecustomize.py ended in 2.5, if your not on 2.5 try it out. (just add one of the path add methods above to the file and drop it in the directory your program is run)
A work around method is mentioned in the post for users of 2.5 and up. </p>

| 24 | 2008-10-30T04:32:52Z | 249,708 | <p>I find in this situation, symlinks, or even copying specific files (packages, modules, extensions) works really well.</p>
<p>It allows the program to emulate being run in the target environment, rather than changing the application to suit the development environment.</p>
<p>Same deal for something like AppEngine.</p>

<p>pip install ruamel.venvgtk
You don't have import anything, the links are setup during installation.</p>
<p>This is especially handy if you are using <code>tox</code>, in that case you only need to include the dependency (for tox):</p>
<pre><code>deps:
pytest
ruamel.venvgtk
</code></pre>
<p>and a newly setup python2.7 environment will have the relevant links included before the tests are run.</p>
<p>More detailed information on how the links are setup can be found in <a href="http://stackoverflow.com/a/27471354/1307905">this answer</a></p>

Translate SVN path to local file system path in Python | 249,330 | <p>I'm writing a utility in Python that will attach changed files in Subversion to an email and send it when a subset of folders that are under source control in SVN have been changed. I am using the pysvn library to access the repository.</p>
<p>I have a copy of the files on my local file system and I do an update to check if the files have changed since the last time the utility was run.</p>
<p>I am at the point where I am translating the path names in SVN to the path names on my local copy.</p>
<p>Currently I have written the following to do the job:</p>
<pre><code>def formatPaths(self, paths):
newPaths = list()
for path in paths:
path = path[len(self.basePath):]
path = path.replace("/", "\\")
newPaths.append(path)
return newPaths
</code></pre>
<p>self.basePath would be something like "/trunk/project1" and I'm looking to just get the relative path of a subset of folders (I.e. folder1 under "/trunk/project1").</p>
<p>Is this a good way to solve this problem or is there some magical function I missed?</p>
| 0 | 2008-10-30T05:07:18Z | 249,444 | <p>Hm... That would do it:</p>
<pre><code>baselen = len(self.basePath)
for path in paths:
path = path[baselen:].replace("/", "\\")
newPaths.append(path)
return newPaths
</code></pre>
<p>If you like, you can do it like this:</p>
<pre><code>baselen = len(self.basePath)
return (path[baselen:].replace("/", "\\") for path in paths)
</code></pre>
<p>Not calculating <code>baselen</code> in every loop iteration is also good practice.</p>

| 0 | 2008-10-30T05:07:18Z | 249,650 | <p>Stay with the slice operator, but do not change the loop variable inside the loop. for fun, try the generator expression (or keep the listcomp).</p>
<pre><code>baselen = len(self.basePath)
return (path[baselen:].replace("/", "\\") for path in paths)

<p>Edit: `lstrip()' is not relevant here. From the <a href="http://docs.python.org/library/stdtypes.html#string-methods" rel="nofollow">manual</a>:</p>
<blockquote>
<p>str.lstrip([chars])</p>
<p>Return a copy of the string with leading characters removed. If chars is omitted or
None, whitespace characters are removed. If given and not None, chars must be a
string; the characters in the string will be stripped from the beginning of the
string this method is called on.</p>

| 0 | 2008-10-30T05:07:18Z | 249,743 | <p>Your specific solution to the path name copy is reasonable, but your general solution to the entire problem could be improved.</p>
<p>I would <code>easy_install anyvc</code>, a library developed for the <a href="http://pida.co.uk/" rel="nofollow">PIDA IDE</a> which is a uniform python interface into version control systems, and use it instead:</p>
<pre><code>from anyvc import Subversion
vc = Subversion('/trunk')
modified = [f.relpath for f in vc.list() if f.state != 'clean']
for f in modified:
print f.relpath # the relative path of the file to the source root
</code></pre>
<p>Additionally, I would probably attach a diff to an email rather than the actual file. But I guess that's your choice.</p>

Python with PIL and Libjpeg on Leopard | 249,388 | <p>I'm having trouble getting pictures supported with PIL - it throws me this:</p>
<pre><code>IOError: decoder jpeg not available
</code></pre>
<p>I installed PIL from binary, not realizing I needed libjpeg.</p>
<p>I installed libjpeg and freetype2 through fink. </p>
<p>I tried to reinstall PIL using instructions from <a href="http://timhatch.com/" rel="nofollow">http://timhatch.com/</a> (bottom of the page)</p>
<ul>
<li>Download PIL 1.1.6 source package and have the Developer Tools already installed</li>
<li><p>Patch setup.py with this patch so it can find the Freetype you already have.</p>
<p><code>patch -p0 < leopard_freetype2.diff</code></p></li>
<li>sudo apt-get install libjpeg if you have fink (otherwise, build by hand and adjust paths)</li>
</ul>
<p>But I'm still getting the same error. </p>
<p>I'm on Leopard PPC. </p>
| 3 | 2008-10-30T06:00:14Z | 249,406 | <p>Is the python path still looking at the old binary version of libjpeg?</p>
<p>You will need to modify it to point to the new place if it is.</p>
<p>When you compiled the new version of the PIL did it say that it found libjpeg? It will compile happily without it (iirc) and the first sign of trouble you will see is at include time.</p>
<p>You will need to adjust the path at ./configure time.</p>
<p>The diff might just not work for you. You should test some more and then perhaps file a bug.</p>

| 3 | 2008-10-30T06:00:14Z | 249,414 | <p>I had the similar 'jpeg decoder problem' recently when deploying a django project on a product RHEL box that required PIL. I downloaded PIL, and ran 'python setup.py install' instantly, and was happy that everything was working, until I bumped into the problem. Solution: libjpeg was already installed on the system, so I installed libjpeg-devel. I went back into the source of PIL and ran 'python setup.py build', at the end of which, in the output where it shows whether PIL configure was able to detect support for jpeg, gif, freetype, etc, it said that jpeg support was ok. After installing PIL, it worked fine.</p>

| 3 | 2008-10-30T06:00:14Z | 4,533,995 | <p>I have stuck to this problem for quite a few hours today. And my advice is do NOT do trial and error again and again, unless u could fix the problem in first 15 minutes.</p>
<p>there are a few tools for you to diagnose the problem:</p>
<p>1.check the if jpeg lib architcture matches your machine architecture:</p>
<pre><code>file /usr/local/lib/libjpeg.7.dylib
</code></pre>
<p>2.check if the _imaging.so acutally linked to your compiled jpeg lib</p>
<pre><code>cd ImageSrc
python setup.py build_ext -i
otool -L PIL/_imaging.so
</code></pre>
<p>3.try to import _imaging.so and see what's the problem</p>
<pre><code>cd PIL
python
import _imaging
</code></pre>
<p>4.finally, try to remove all previous installed PIL* from python "site-package" directory to make sure set up does work</p>
<pre><code>python setup.py install
</code></pre>
<p>For me, it's due to I am using 32 bit python on snow leopard, and solved the problem by install jpeg lib in this way:</p>
<pre><code>./configure CFLAGS="-arch i386" --enable-shared --enable-static
</code></pre>

How to determine if a directory is on same partition | 249,775 | <p>Say I have an input file, and a target directory. How do I determine if the input file is on the same hard-drive (or partition) as the target directory?</p>
<p>What I want to do is the copy a file if it's on a different, but move it if it's the same. For example:</p>
<pre><code>target_directory = "/Volumes/externalDrive/something/"
input_foldername, input_filename = os.path.split(input_file)
if same_partition(input_foldername, target_directory):
copy(input_file, target_directory)
else:
move(input_file, target_directory)
</code></pre>
<p><hr /></p>
<p>Thanks to CesarB's answer, the <code>same_partition</code> function implemented:</p>
<pre><code>import os
def same_partition(f1, f2):
return os.stat(f1).st_dev == os.stat(f2).st_dev
</code></pre>
| 6 | 2008-10-30T10:45:42Z | 249,796 | <p>In C, you would use <code>stat()</code> and compare the <code>st_dev</code> field. In python, <code>os.stat</code> should do the same.</p>

| 6 | 2008-10-30T10:45:42Z | 250,149 | <p>Another way is the âbetter to ask forgiveness than permissionâ approachâjust try to rename it, and if that fails, catch the appropriate <code>OSError</code> and try the copy approach. ie:</p>
<pre><code>import errno
try:
os.rename(source, dest):
except IOError, ex:
if ex.errno == errno.EXDEV:
# perform the copy instead.
</code></pre>
<p>This has the advantage that it will also work on Windows, where st_dev is always 0 for all partitions.</p>
<p>Note that if you actually want to copy and then delete the source file (ie. perform a move), rather than just copy, then shutil.move will already do what you want:</p>
<pre>
Help on function move in module shutil:
move(src, dst)
Recursively move a file or directory to another location.
If the destination is on our current filesystem, then simply use
rename. Otherwise, copy src to the dst and then remove src.
</pre>
<p>[Edit] Updated due to Matthew Schinckel's comment to mention that shutil.move will delete the source after the copy, which isn't necessarily what is wanted, as the question just mentions copying.</p>

| 1 | 2008-10-30T10:50:32Z | 251,566 | <p>Alternatively, if you're on OS X 10.5, you could use Scripting Bridge to delete files via the Finder. I've done this in Ruby code <a href="http://osx-trash.rubyforge.org/git?p=osx-trash.git;a=blob;f=bin/trash;h=26911131eacafd659b4d760bda1bd4c99dc2f918;hb=HEAD">here</a> via RubyCocoa.

<pre><code>url = NSURL.fileURLWithPath(path)
finder = SBApplication.applicationWithBundleIdentifier("com.apple.Finder")
item = finder.items.objectAtLocation(url)
item.delete

| 1 | 2008-10-30T10:50:32Z | 252,920 | <p>Based upon code from <a href="http://www.cocoadev.com/index.pl?MoveToTrash" rel="nofollow">http://www.cocoadev.com/index.pl?MoveToTrash</a> I have came up with the following:</p>
<pre><code>def get_trash_path(input_file):
path, file = os.path.split(input_file)
if path.startswith("/Volumes/"):
# /Volumes/driveName/.Trashes/<uid>
s = path.split(os.path.sep)
# s[2] is drive name ([0] is empty, [1] is Volumes)
trash_path = os.path.join("/Volumes", s[2], ".Trashes", str(os.getuid()))
if not os.path.isdir(trash_path):
raise IOError("Volume appears to be a network drive (%s could not be found)" % (trash_path))
else:
trash_path = os.path.join(os.getenv("HOME"), ".Trash")
return trash_path
</code></pre>
<p>Fairly basic, and there's a few things that have to be done seperatly, particularly checking if the filename already exist in trash (to avoid overwriting) and the actual moving to trash, but it seems to cover most things (internal, external and network drives)</p>
<p><strong>Update:</strong> I wanted to trash a file in a Python script, so I re-implemented Dave Dribin's solution in Python:</p>
<pre><code>from AppKit import NSURL
from ScriptingBridge import SBApplication
def trashPath(path):
"""Trashes a path using the Finder, via OS X's Scripting Bridge.
"""
targetfile = NSURL.fileURLWithPath_(path)
finder = SBApplication.applicationWithBundleIdentifier_("com.apple.Finder")
items = finder.items().objectAtLocation_(targetfile)
items.delete()

| 30 | 2008-10-30T12:42:10Z | 253,103 | <p>It depends on how the user installs your package. If the user actually runs "setup.py install", it's fairly easy: Just add another subcommand to the install command (say, install_vim), whose run() method will copy the files you want in the places where you want them. You can add your subcommand to install.sub_commands, and pass the command into setup().</p>
<p>If you want a post-install script in a binary, it depends on the type of binary you are creating. For example, bdist_rpm, bdist_wininst, and bdist_msi have support for post-install scripts, because the underlying packing formats support post-install scripts.</p>

<ul>

| 33 | 2008-10-30T13:21:41Z | 250,158 | <p>Just because it is "marketed" (in some general sense) as a special-purpose language for embedded script engines, does not mean that it is limited to that. In fact, WoW could probably just as well have chosen Python as their embedded scripting language.</p>

| 33 | 2008-10-30T13:21:41Z | 250,168 | <p>It's probably because Lua was designed as a scripting and extension language. On the <a href="http://www.lua.org/about.html">official site</a> it's described as a powerful, fast, light-weight, embeddable scripting language. There's nothing stopping you from writing general purpose programs for it (if I recall correctly it ships with an interpreter and compiler), but the language designers intended it to be used mainly as an embedded language (hence being light-weight and all)</p>

| 33 | 2008-10-30T13:21:41Z | 252,900 | <p>Lua is a cool language, light-weight and extremely fast!</p>
<p>But the point is: <strong>Is performance so important for those
tasks you mentioned?</strong></p>
<ul>
<li>Renaming a bunch of files</li>
<li>Download some files from the web</li>
<li>Webscraping</li>
</ul>
<p>You write those programs once, and run them once, too maybe.
Why do you care about performance so much for a run-once program?</p>
<p>For example:</p>
<ol>
<li>Cost 3 hours to write a C/C++ program, to handle data once, the program will take 1 hour to run.</li>
<li>Cost 30 Minute to write a Python program to handle data once, the program will take 10 hours to run.</li>
</ol>
<p>If you choose the first, you save the time to run the program,
but you cost your time to develop the program.</p>
<p>On the other hand, if you choose the second, you waste time to run
the program, but you can do other things when the program is
running. <strong>How about play World of Warcraft, kill monsters
with your warlock? Eat my D.O.T</strong>! :P</p>
<p>That's it! Although Lua is not so difficult to write, everything about Lua is designed to be efficient.And what's more, there are little modules for Lua, but there are so many modules for Python. You don't want to port a C library for Lua just for a run-once program, do you? Instead, choose Python and use those module to achieve your task easily might be a better idea.</p>
<p>FYI: Actually, I have tried to use Lua to do webscraping,
but finally, I realized I do not have to care so much about language performance. <strong>The bottleneck of webscraping is
not on the performance of the language</strong>. The bottleneck is on
network I/O, HTML parsing and multitasking. All I have to do
is make sure the program works and find the bottleneck.
Finally, I chose Python rather than Lua. There is so
many excellent Python modules; I have no reason to build my
own.</p>
<p>According to my experience about webscraping, I chose
Twisted for network I/O and lxml for html parsing as the backend
of my webscraping program. I have wrote an article for an introduction to this technology.</p>
<p><a href="http://blog.ez2learn.com/2009/09/26/the-best-choice-to-grab-data-from-websites-python-twisted-lxml/">The best choice to grab data from websites: Python + Twisted + lxml</a></p>
<p>Hope this is helpful.</p>

| 33 | 2008-10-30T13:21:41Z | 253,659 | <p>I think the answer about it being a "marketing" thing is probably correct, along with the lack of a large set of libraries to choose from. I would like to point out another case of this: Ruby. Ruby is meant to be a general purpose scripting language. The problem is that since Ruby on Rails has risen to be so popular, it is becoming hard to find something that is unrelated to Rails. I'm afraid Lua will suffer this as well, being popular because of a few major things using it, but never able to break free of that stigma.</p>

| 33 | 2008-10-30T13:21:41Z | 253,755 | <p>Lua has fewer libraries than Python. But be sure to have a look at <a href="http://luaforge.net/">LuaForge</a>. It has a lot of interesting libs, like <a href="http://luaforge.net/projects/luacurl/">LuaCURL</a>, <a href="http://wxlua.sourceforge.net/">wxLua</a> or <a href="http://luaforge.net/projects/getopt/">getopt</a>.</p>
<p>Then, visit <a href="http://luarocks.org/">LuaRocks</a>, the package management system for Lua. With it, you can search and install most mature Lua modules with dependencies. It feels like <a href="http://en.wikipedia.org/wiki/RubyGems">RubyGems</a> or <a href="http://en.wikipedia.org/wiki/Aptitude%5F%28software%29">aptitude</a>.</p>
<p>The site <a href="http://lua-users.org/">lua-users.org</a> has a lot of interesting resources too, like tutorials or the <a href="http://lua-users.org/wiki">Lua Wiki</a>.</p>
<p>What I like about Lua is not its speed, it's its minimal core language, flexibility and extensibility.</p>
<p>That said, I would probably use Python for the tasks you mentionned because of the larger community doing such things in Python.</p>

| 33 | 2008-10-30T13:21:41Z | 326,660 | <p>This is a sociological question, not a programming question.</p>
<p>I use Lua for general-purpose scripting almost exclusively. But I had to write a few hundred lines of code so that Lua would play better with the shell. This included such tricks as </p>
<ul>
<li>Quoting a string so it is seen as one word by the shell</li>
<li>Writing a function to capture the output of a command as in shell $(command)</li>
<li>Writing a function to crawl the filesystem using the Lua posix library and expand shell globbing patterns</li>
</ul>
<p>(For those who may be interested, I've left the code in my <a href="http://www.cs.tufts.edu/~nr/drop/lua/">Lua drop box</a>, which also contains some other stuff. The interesting stuff is probably in <code>osutil</code> in <code>os.quote</code>, <code>os.runf</code>, <code>os.capture</code>, and maybe <code>os.execve</code>. The globbing is in <a href="http://www.cs.tufts.edu/~nr/drop/lua/posixutil.lua"><code>posixutil.lua</code></a>. They both use Luiz Henrique de Figuereido's <a href="http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/">Lua Posix library</a>.)</p>
<p>To me, the extra effort is worth it because I can deal with simple syntax and great data structures. To others, a more direct connection with the shell might be preferred.</p>

| 33 | 2008-10-30T13:21:41Z | 568,728 | <p>There has been a recent push to create a batteries included installation for Lua on Windows. The result can be found at the <a href="http://luaforge.net/projects/luaforwindows/" rel="nofollow">Lua for Windows</a> project at LuaForge. It includes the interpreter and a large collection of extra modules allowing useful scripts and applications to be written and used out of the box.</p>
<p>I know that various Linux distros are including Lua and some modules now, and more to come.</p>
<p>There are also a couple of proposed module libraries under discussion in the mailing list, but the community hasn't yet settled on one as the "official" mechanism.</p>
<p>I use Lua both as a scripting language and as the "main" loop of my typical application, supported by one or more DLLs containing code that was better implemented in C, or wrapping existing libraries or API functions that are needed by a particular project. Used with a GUI toolkit such as <a href="https://sourceforge.net/projects/iup/" rel="nofollow">IUP</a> or <a href="http://wxlua.sourceforge.net/" rel="nofollow">wxLua</a> (a Lua binding for wxWindows), Lua makes writing small to mid-sized GUI applications quite pleasant.</p>

| 33 | 2008-10-30T13:21:41Z | 781,316 | <p>In order for Lua to be easy to embed it has to have few dependencies and be small. That makes it poorly suited as a general purpose scripting language. Because using it as a general purpose script language would require a lot of standard libraries. But if Lua had a lot of standard libraries it would be harder to embed (due to dependencies and memory footprint.)</p>

It is used as a scripting language for some utilities in the TeX Live distribution, be it only because now there is a <code>luatex</code> binary, available on all platforms, that can also be used as a Lua interpreter (with some vital modules added â slnunicode, luafilesystem, etc.) That's very important for Windows installations, that relied on additional Unix scripting tools earlier (ActivePerl, etc.) The ConTeXt macro language uses Lua scripts extensively nowadays.</p>

Your calling, "self.request.get('links')" twice.</p>
<p>So adding:</p>
<pre><code>unsplitlinks = self.request.get('links')

<p>And referencing, "unsplitlinks" could help.</p>
<p>Other than that the loop is the only area I see that would be a target for optimization.
Is it possible to prep the data and then add it to the db at once, instead of doing a db add per link? (I assume the .put() command adds the link to the database)</p>

Python Regex - How to Get Positions of Matches | 250,271 | <p>How can I get the start and end positions of all matches using the <code>re</code> module? For example given the pattern <code>r'[a-z]'</code> and the string <code>'a1b2c3d4'</code> I'd want to get the positions where it finds each letter (ideally I'd like to get the text of the match back too).</p>
| 50 | 2008-10-30T14:04:33Z | 250,303 | <pre><code>import re
p = re.compile("[a-z]")
for m in p.finditer('a1b2c3d4'):

| 50 | 2008-10-30T14:04:33Z | 250,306 | <p>Taken from </p>
<p><a href="http://docs.python.org/3.3/howto/regex.html"><em>Regular Expression HOWTO</em></a></p>
<blockquote>
<p>span() returns both start and end indexes in a single tuple. Since the
match method only checks if the RE matches at the start of a string,
start() will always be zero. However, the search method of RegexObject
instances scans through the string, so the match may not start at zero
in that case.</p>
</blockquote>
<pre><code>>>> p = re.compile('[a-z]+')
>>> print p.match('::: message')
None
>>> m = p.search('::: message') ; print m
<re.MatchObject instance at 80c9650>
>>> m.group()
'message'
>>> m.span()
(4, 11)
</code></pre>
<p>Combine that with:</p>
<p>In Python 2.2, the finditer() method is also available, returning a sequence of MatchObject instances as an iterator.</p>
<pre><code>>>> p = re.compile( ... )
>>> iterator = p.finditer('12 drummers drumming, 11 ... 10 ...')
>>> iterator
<callable-iterator object at 0x401833ac>
>>> for match in iterator:
... print match.span()
...
(0, 2)
(22, 24)
(29, 31)
</code></pre>
<p>you should be able to do something on the order of</p>
<pre><code>for match in re.finditer(r'[a-z]', 'a1b2c3d4'):
print match.span()

Sorry, missed the line where you mentioned paramiko.
The following module is simply an implementation of the scp protocol for paramiko.
If you don't want to use paramiko or conch (the only ssh implementations I know of for python), you could rework this to run over a regular ssh session using pipes.</p>

How to scp in python? | 250,283 | <p>What's the most pythonic way to scp a file in Python? The only route I'm aware of is </p>
<pre><code>os.system('scp "%s" "%s:%s"' % (localfile, remotehost, remotefile) )
</code></pre>
<p>which is a hack, and which doesn't work outside linux-like systems, and which needs help from the Pexpect module to avoid password prompts unless you already have passwordless SSH set up to the remote host.</p>

Truncate a string without ending in the middle of a word | 250,357 | <p>I am looking for a way to truncate a string in Python that will not cut off the string in the middle of a word.</p>
<p>For example:</p>
<pre>
Original: "This is really awesome."
"Dumb" truncate: "This is real..."
"Smart" truncate: "This is really..."
</pre>
<p>I'm looking for a way to accomplish the "smart" truncate from above.</p>
| 31 | 2008-10-30T14:32:20Z | 250,373 | <p>I actually wrote a solution for this on a recent project of mine. I've compressed the majority of it down to be a little smaller.</p>
<pre><code>def smart_truncate(content, length=100, suffix='...'):
if len(content) <= length:
return content
else:
return ' '.join(content[:length+1].split(' ')[0:-1]) + suffix
</code></pre>
<p>What happens is the if-statement checks if your content is already less than the cutoff point. If it's not, it truncates to the desired length, splits on the space, removes the last element (so that you don't cut off a word), and then joins it back together (while tacking on the '...').</p>

| 31 | 2008-10-30T14:32:20Z | 250,684 | <p>There are a few subtleties that may or may not be issues for you, such as handling of tabs (Eg. if you're displaying them as 8 spaces, but treating them as 1 character internally), handling various flavours of breaking and non-breaking whitespace, or allowing breaking on hyphenation etc. If any of this is desirable, you may want to take a look at the textwrap module. eg:</p>
<pre><code>def truncate(text, max_size):
if len(text) <= max_size:
return text
return textwrap.wrap(text, max_size-3)[0] + "..."
</code></pre>
<p>The default behaviour for words greater than max_size is to break them (making max_size a hard limit). You can change to the soft limit used by some of the other solutions here by passing break_long_words=False to wrap(), in which case it will return the whole word. If you want this behaviour change the last line to:</p>
<pre><code> lines = textwrap.wrap(text, max_size-3, break_long_words=False)
return lines[0] + ("..." if len(lines)>1 else "")
</code></pre>
<p>There are a few other options like expand_tabs that may be of interest depending on the exact behaviour you want.</p>

What do you like about Django? | 250,397 | <p>I started to learn Django a few days ago, and as i dive into it it seems that I'm starting to like it even more.<br />
Trying to migrate from other language.
I won't say which one, as the purpose of this question is not to bash anything.</p>

| 6 | 2008-10-30T14:41:38Z | 250,459 | <p><strong><em>What do I like about it :</em></strong></p>
<ul>
<li>Very simple ORM</li>
<li>clear separation of template / controller</li>
<li>django-admin</li>
<li>pluggable apps : it seems to me that the Django community really nailed that one !</li>
</ul>
<p><strong><em>What made me switch :</em></strong></p>
<ul>
<li>mainly curiosity</li>
<li>I heard a lot of good things about it from a colleague</li>
<li>I wanted something more lightweight than the Java I do for a living</li>
<li>I had a side project heavily data-driven for which the Django-Admin interface is very useful</li>
</ul>
<p><strong><em>What features I'd like :</em></strong></p>
<ul>
<li>better / simpler control of the transactions (configuring different types of transactions (read only / read write / some tweaking here and there) isnt as easy as i am used to. Having a session in view model, where the transaction is still open in the view doesnt make me all that comfortable, I would prefer if the transactions didnt leave a service layer. But again, there isnt really a service layer in the Django model.</li>
<li>better model for business logic (maybe that's just me, but I miss the service oriented approach of enterprise java, I never know if I should put the business logic in the view, in the form or in the model. None of those solution make me feel warm and fuzzy ... at the same time, I dont have heavy business logic in the application I develop for the moment, and I would probably still use Java for those)</li>
<li>stability (in the sense of not changing, not in the sense of not crashing). Again, coming from Java, where I'm still working on Java 1.4 for a lot of projects, having a project that just released 1.0 and all the refactoring that went with it is not very reassuring. It did take some work to follow trunk and using 0.96 was not particularly compelling. I dont think I would feel comfortable to use it on a mission critical enterprise project yet.</li>
</ul>
<p>I realize that there is quite a few improvements that I would like. Dont understand me wrong, I love Django and I will stick to it for a lot of projects. I jsut wont put it everywhere yet ...</p>

| 6 | 2008-10-30T14:41:38Z | 250,461 | <h3>What do you like about it?</h3>
<p>URL dispatching: I was never a big fan of "/foo.php" is the file "foo.php" on my server, and if I want nicer URLs I need to mess around with mod_rewrite and keep that in line with what my logic in foo expects.</p>
<p>ORM: Because 90%+ of your queries, in my experience, do not need to be written by hand. Smart caching is much more important for performance, in general. You can <em>always</em> drop to raw SQL as needed.</p>
<p>Middleware and Signals: Easy to extend most parts of the request / response / view / render cycle without touching Django code itself.</p>
<h3>What made you switch/use it?</h3>
<p>It came out when I was disappointed with the Python web framework offerings. An easy sell for me.</p>
<h3>How fast is it in production?</h3>
<p>Hmm, to be honest, I've never cared too much. The webserver part of your app is (in my opinion) always the easiest to scale. As long as you use 'best practices' and share nothing, all you need to do is add a software load balancer and you can add new webservers until the cows come home. The first bottleneck people generally hit is database load - but Django gives you great caching APIs that help you alleviate that.</p>
<p>That said, I only skimmed this but it seems faster than Rails and the well known PHP frameworks: <a href="http://wiki.rubyonrails.org/rails/pages/Framework+Performance">http://wiki.rubyonrails.org/rails/pages/Framework+Performance</a></p>
<h3>How hard is it to master it?</h3>
<p>I guess it depends how you define 'master'. The documentation is great, over the course of a decent sized site/app I think you'll use a little bit of everything, which is a great start.</p>

<p>The excellent Documentation. Together with help from stackoverflow I have learned a lot in only a few days.
It writting in Python.
It has the wonderful contrib.admin which is even modular and extensible to embed it into the web app proper.</p>
<h2>Dislikes</h2>
<p>None so far. I am still enchanted</p>
<h2>Switch</h2>
<p>Its my first web framework, so no switch. After using Python for some years Django seemed the natural selection to me, mainly for its clean design.</p>

<li>the templates, specifically the inheritance feature, was amazing after dealing with jsps</li>

<h2>What made you switch/use it?</h2>
<p>A friend had been following its progress before it was publicly released, and I've been using it for personal projects ever since.</p>
<h2>What features you would like it to have that aren't there?</h2>
<p>I realize this isn't a trivial problem, and I think Google summer of codes have been spent on this, but I would like to see better ways to evolve the db (which rails seems to do a pretty good job of).</p>
<h2>What would make you switch to it?</h2>
<p>I already use it at home, and I don't make those decisions at work.</p>
<h2>How fast is it in production?</h2>
<p>I've never run into issues, though for the most part django seems to stay out of the way, so performance seems based more on python or the db.</p>
<h2>How hard is it to master it? </h2>
<p>The documentation is pretty amazing, and enough people use it that answers are often available when that doesn't help. Additionally, when I've had to go into the source code, its been clean and documented as well, so I would say its easier to master than most frameworks, web based or otherwise.</p>

<li>Pythonic (I can easily grok the language) and thus extend any part easily</li>
<li>Documentation,</li>
<li>community (I belong to the french one and they're very nice)</li>
<li>a full load of projects around it</li>
<li>full-integrated test engine. You can almost test a whole application without firing a web browser, just by writing tests.</li>
<li>the custom commands just rock. It allows you to perform custom tasks very easily, in a snap. I often use it to run batch tasks (cleanup a database, for example, or check for integrity on a production server - tests use their own database, not the actual data in your application).</li>

<li>had a RSI at the back of my hand, very painful. after switching to a semicolon-free language, it vanished (it's TRUE!)</li>
<li>much more solid developpement (TDD), and faster (you can buid a CMS in minutes) - as many other web framework, though.</li>
</ul>
<p>Dislikes:</p>
<ul>
<li>no smooth data model migration. You often have to change your model because of an unexpected feature. That is painful, and you have to build it by hand, and it may be risky sometimes.</li>
</ul>
<p>How hard to master?</p>
<ul>
<li>If you already have Python skills, you can build up things in a few hours.</li>
<li>If you don't, first dive into Python (heh) - that'd take a few days.</li>
<li>"Mastering" it may take some time... And you often discover gems in Django documentation that will make you yell "I love Django!" (well, it works for me)</li>

How to specify relations using SQLAlchemy declarative syntax? | 250,398 | <p>I can't find any proper documentation on how to specify relations
using the declarative syntax of SQLAlchemy.. Is it unsupported? That is, should I use the "traditional" syntax?<br />
I am looking for a way to specify relations at a higher level, avoiding having to mess with foreign keys etc.. I'd like to just declare "addresses = OneToMany(Address)" and let the framework handle the details.. I know that Elixir can do that, but I was wondering if "plain" SQLA could do it too.<br />
Thanks for your help!</p>
| 3 | 2008-10-30T14:41:50Z | 251,077 | <p>Assuming you are referring to <a href="http://www.sqlalchemy.org/docs/04/plugins.html#plugins_declarative" rel="nofollow">the declarative plugin</a>, where everything I am about to say is documented with examples:</p>
<pre><code>class User(Base):
__tablename__ = 'users'
id = Column('id', Integer, primary_key=True)
addresses = relation("Address", backref="user")
class Address(Base):
__tablename__ = 'addresses'
id = Column('id', Integer, primary_key=True)
user_id = Column('user_id', Integer, ForeignKey('users.id'))

| 3 | 2008-10-30T14:41:50Z | 1,094,626 | <p>Look at the "Configuring Relations" section of the <a href="http://www.sqlalchemy.org/docs/05/reference/ext/declarative.html" rel="nofollow">Declarative docs</a>. Not quite as high level as "OneToMany" but better than fully specifying the relation. </p>

id = Column(Integer, primary_key=True)
email = Column(String(50))
user_id = Column(Integer, ForeignKey('users.id'))

Is it possible to communicate with a sub subprocess with subprocess.Popen? | 250,700 | <p>I'm trying to write a python script that packages our software. This script needs to build our product, and package it. Currently we have other scripts that do each piece individually which include csh, and perl scripts. One such script is run like:</p>
<pre><code>sudo mod args
</code></pre>
<p>where mod is a perl script; so in python I would do </p>
<pre><code>proc = Popen(['sudo', 'mod', '-p', '-c', 'noresource', '-u', 'dtt', '-Q'], stderr=PIPE, stdout=PIPE, stdin=PIPE)
</code></pre>
<p>The problem is that this mod script needs a few questions answered. For this I thought that the traditional </p>
<pre><code>(stdout, stderr) = proc.communicate(input='y')
</code></pre>
<p>would work. I don't think it's working because the process that Popen is controlling is sudo, not the mod script that is asking the question. Is there any way to communicate with the mod script and still run it through sudo?</p>
| 5 | 2008-10-30T15:50:51Z | 250,804 | <p>The simplest thing to do would be the run the controlling script (the Python script) via <code>sudo</code>. Are you able to do that, or is that not an option?</p>

| 5 | 2008-10-30T15:50:51Z | 250,819 | <p>I think you should remove the <code>sudo</code> in your <code>Popen</code> call and require the user of <em>your</em> script to type <code>sudo</code>.</p>
<p>This additionally makes more explicit the need for elevated privileges in your script, instead of hiding it inside <code>Popen</code>.</p>

<li>Is sudo asking you for a password?</li>

<p>Because these kind of things are not handled as normal over the pipe.</p>
<p>A solution for both of these might be <a href="http://www.noah.org/wiki/Pexpect" rel="nofollow">Pexpect</a>, which is rather expert at handling funny scripts that ask for passwords, and various other input issues.</p>

How to get a function name as a string in Python? | 251,464 | <p>In Python, how do I get a function name as a string without calling the function?</p>
<pre><code>def my_function():

</code></pre>
<p>There are also other fun properties of functions. Type <code>dir(func_name)</code> to list them. <code>func_name.func_code.co_code</code> is the compiled function, stored as a string.</p>
<pre><code>import dis
dis.dis(my_function)
</code></pre>
<p>will display the code in <em>almost</em> human readable format. :)</p>

| 306 | 2008-10-30T19:38:24Z | 255,297 | <pre><code>my_function.__name__
</code></pre>
<p>Using <code>__name__</code> is the preferred method as it applies uniformly. Unlike <code>func_name</code>, it works on built-in functions as well:</p>
<pre><code>>>> import time
>>> time.time.func_name
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'builtin_function_or_method' object has no attribute 'func_name'
>>> time.time.__name__
'time'
</code></pre>
<p>Also the double underscores indicate to the reader this is a special attribute. As a bonus, classes and modules have a <code>__name__</code> attribute too, so you only have remember one special name.</p>

| 306 | 2008-10-30T19:38:24Z | 38,453,402 | <p>I like using a function decorator.
I added a class, which also times the function time. Assume gLog is a standard python logger:</p>
<pre><code>class EnterExitLog():
def __init__(self, funcName):
self.funcName = funcName
def __enter__(self):
gLog.debug('Started: %s' % self.funcName)
self.init_time = datetime.datetime.now()
return self
def __exit__(self, type, value, tb):
gLog.debug('Finished: %s in: %s seconds' % (self.funcName, datetime.datetime.now() - self.init_time))
def func_timer_decorator(func):
def func_wrapper(*args, **kwargs):
with EnterExitLog(func.__name__):
return func(*args, **kwargs)
return func_wrapper
</code></pre>
<p>so now all you have to do with your function is decorate it and voila</p>
<pre><code>@func_timer_decorator
def my_func():

script languages on windows mobile - something similar to python @ nokia s60 | 251,506 | <p>I try to find something similar to nokia's <strong>python for windows mobile</strong> based devices - a script interpreter [in this case also able to create standalone apps] with easy access to all phone interfaces - ability to make a phone call, send SMS, make a photo, send a file over GPRS, etc...</p>
<p>While there is 2.5 <strong>pythonce</strong> available for windows mobile it is pure python interpreter and what I look for are all those "libraries" that nokia's python has like "import camera", "import messaging", ability to control the phone programatically. Also the bluetooth console of nokia python is great.</p>
<p>I do not want to use .NET CF as even there (AFAIK) to control camera you need to use some indirect methods (for example: <a href="http://blogs.msdn.com/marcpe/archive/2006/03/03/542941.aspx" rel="nofollow">http://blogs.msdn.com/marcpe/archive/2006/03/03/542941.aspx</a>). </p>

Possible Google Riddle? | 252,221 | <p>My friend was given this free google website optimizer tshirt and came to me to try and figure out what the front logo meant.</p>
<p><a href="http://2.bp.blogspot.com/_iQVgmEEAit4/SPkKHA3e8fI/AAAAAAAAAB8/ugUerJjuBw8/s1600-h/GWO-tshirt.jpg" rel="nofollow">t-shirt</a></p>
<p>So, I have a couple of guesses as to what it means, but I was just wondering if there is something more.</p>
<p>My first guess is that each block represents a page layout, and the logo "You should test that" just means that you should use google website optimizer to test which is the best layout. I hope that this isn't the answer, it just seems to simple and unsatisfying.</p>
<p>Well, I've spent the past hour trying to figure out if there is any deeper meaning, but to no avail. So, I'm here hoping that someone might be able to help.</p>
<p>I did though write a program to see if the blocks represent something in binary. I'll post the code below. My code tests every permutation of reading a block as 4 bits, and then tries to interpret these bits as letters, hex, and ip addresses.</p>

Possible Google Riddle? | 252,221 | <p>My friend was given this free google website optimizer tshirt and came to me to try and figure out what the front logo meant.</p>

<p>So, I have a couple of guesses as to what it means, but I was just wondering if there is something more.</p>
<p>My first guess is that each block represents a page layout, and the logo "You should test that" just means that you should use google website optimizer to test which is the best layout. I hope that this isn't the answer, it just seems to simple and unsatisfying.</p>
<p>Well, I've spent the past hour trying to figure out if there is any deeper meaning, but to no avail. So, I'm here hoping that someone might be able to help.</p>
<p>I did though write a program to see if the blocks represent something in binary. I'll post the code below. My code tests every permutation of reading a block as 4 bits, and then tries to interpret these bits as letters, hex, and ip addresses.</p>
<p>I hope someone knows better.</p>

<p>If that's OK, try running:</p>
<pre><code>python -v -v test.py
