At first I was going to post the following:
I just discovered the inspect module, which contains the isfunction and
ismethod functions. For some reason, I used to be under the impression
that Python methods are no different from Python functions. Naturally,
I wondered why both of these needed to

I'm surprised no one has mentioned neat-er, more pythonic ways of doing
this. I'm also surprised no one mentioned regular expressions. Regular
expressions are really powerful for searching and manipulating text.
Here is where I learned most of the stuff I know about regular
expressions:

No offense. I didn't mean there was anything wrong with your way, just
that it wasn't "neat". By that, I meant, you were still using lots of
for loops and if blocks.

Python has a csv module. I'm not sure if you're already using that or
if it would be useful to you:

Is your declaration of ABC supposed to have some_super as one of the
base classes? Your constructor has some_super as a parameter. What is
this supposed to mean in light of the declaration for ABC?
If you are trying to customize the base class of ABC by passing an
argument to the constructor of AB

MyClass.py has to be on your "python path". Your python path is a list

I would really like to highlight something Tal has already said: Python
strings are immutable. That means if you construct a string object, you
don't have to worry about someone else going in and changing that
object. What might happen, however, is that someone might reassign a
variable you have wh

Is there a convention for how to document function (or method)
parameters in doc strings? Recently, I've been doing alot of PHP
programming, and in PHPdoc, you'd do it like this:
/*
* @param type $foo Description.
*
* @return type Description.
*/
function bar($foo) {
...
}
Is there an equiv
