Why does the zip archive itself need to be served from Django? A 90's era CGI script to generate a zip and spit it to stdout is really all that's required here, at least as far as I can see.</p>

Static class variables in Python | 68,645 | <p>Is it possible to have static class variables or methods in python? What syntax is required to do this?</p>
| 1,015 | 2008-09-16T01:46:36Z | 68,747 | <p>Personally I would use a classmethod whenever I needed a static method. Mainly because I get the class as an argument.</p>
<pre><code>class myObj(object):
def myMethod(cls)
...
myMethod = classmethod(myMethod)
</code></pre>
<p>or use a decorator</p>
<pre><code>class myObj(object):
@classmethod

| 1,015 | 2008-09-16T01:46:36Z | 68,770 | <p>Static methods in python are called <a href="http://pyref.infogami.com/classmethod" rel="nofollow">classmethod</a>s. Take a look at the following code</p>
<pre><code>class MyClass:
def myInstanceMethod(self):
print 'output from an instance method'
@classmethod

| 1,015 | 2008-09-16T01:46:36Z | 69,067 | <p>@Blair Conrad said static variables declared inside the class definition, but not inside a method are class or "static" variables:</p>
<pre><code>>>> class Test(object):
... i = 3
...
>>> Test.i
3
</code></pre>
<p>There are a few gotcha's here. Carrying on from the example above:</p>

<p>Some primitive object types like integers, floats, strings, and touples are immutable in Python. This means that the object that is referred to by a given name cannot change if it is of one of the aforementione... | 2 | 2008-09-17T04:01:08Z | [

| 1,015 | 2008-09-16T01:46:36Z | 81,002 | <p>You can also add class variables to classes on the fly</p>
<pre><code>>>> class X:
... pass
...
>>> X.bar = 0
>>> x = X()

0
