I need a really good reason to use Python | 249,064 | <p>I have been trying to make a case for using Python at my work. We use C# and ASP.NET for basically all of our development. 80% or more of our projects are web applications.

<p>Despite the fact that Python is my current first choice language, I am afraid I find myself on the side of your boss! Sorry.</p>

Set it up so something like deploying builds, or shuffling backups, or whatever is done with Python.</p>

So let's look at Things You Can Leverage Using Python:</p>

<li>Google App Engine</li>
<li>SciPy</li>
<li>pywinauto</li>
<li>django</li>

Good programmers can be successful in a variety of languages, and you'll find successful projects in almost any language. You won't find the failures that much because those projects just go away never to be heard of again. If you're looking for a new language because... | 1 | 2008-10-30T04:27:55Z | [

In fact many Java people started using it first that way. Its dynamic scripting nature makes it a great fit for unit tests.

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.

<pre><code>... r'^browse/(?P<match>.+)/$' ...

<p>The '\w' will only match 'word' characters, but the '.' will match anything.</p>
