True but there is a nice module which handles some common usages.
It's called 'inspect' and somewhat resembles the java-API.

>>> import inspect
>>> help(inspect)
Help on module inspect:

NAME
    inspect - Get useful information from live Python objects.

FILE
    /usr/lib/python2.2/inspect.py

DESCRIPTION
    This module encapsulates the interface provided by the internal
special
    attributes (func_*, co_*, im_*, tb_*, etc.) in a friendlier fashion.
    It also provides some help for examining source code and class
    layout.

HTH,
