The inspect module should provide everything you need here.

  inspect -- Inspect live objects 

    New in version 2.1. 


    The inspect module provides several useful functions to help get
    information about live objects such as modules, classes, methods,
    functions, tracebacks, frame objects, and code objects. For
    example, it can help you examine the contents of a class, retrieve
    the source code of a method, extract and format the argument list
    for a function, or get all the information you need to display a
    detailed traceback.
