Python code for documenting Python classes?

[T. Bridgman]

Just so I don't try to re-invent the wheel...

Does anyone know of a Python program for documenting Python classes?

While it's usually easy to identify the methods in a particular class, 
it is often difficult to identify all the data members since they don't 
get listed in header files as in C++.  In particular, I'm looking for 
something that could list out all the classes, methods, and data 
members in a module, perhaps in a format similar to a C++ header:

class 1 (subclass)
 data members
   member 1: list
   member 2: sequence
   member 3: Float32
 methods
   method 1 (parmlist)
   method 2 (parmlist)
   method 3 (parmlist)

This would facilitate documenting the classes.

Naturally, I'd like something that can also recognize classes from 
other modules (particularly NumPy).

Thanks,
Tom
