Another very nice option is to use ipython:

ipython
In [1]: import numpy
In [2]: numpy.matrix?
In [2]: numpy.matrix??

One ? gives some basic information:
Type:           type
Base Class:     <type 'type'>
String Form:    <class 'numpy.core.defmatrix.matrix'>
Namespace:      Interactive
File:
/home/abaecker/BUILDS3/BuildDir/inst_numpy/lib/python2.4/site-packages/numpy/core/defmatrix.py

(and normally a doc-string, if there is one)
and ?? shows you the code.

Best, Arnd
