the sys module might be what you're looking for.

excerpt from an ipython session:

In [1]:import pygame
In [2]:import sys 
In [3]:sys.modules

Out[3]:
{'ArrayPrinter': <module 'ArrayPrinter' from '/usr/lib/python2.3/site-packages/Numeric/ArrayPrinter.pyc'>,
 'IPython': <module 'IPython' from '/usr/lib/python2.3/site-packages/IPython/__init__.pyc'>,
 'IPython.ColorANSI': <module 'IPython.ColorANSI' from '/usr/lib/python2.3/site-packages/IPython/ColorANSI.pyc'>,
[SNIP]

you get a dict of imported modules (as well as built-in ones, though
it's easy to filter them out)
