Sure -- use my Signature module:

  >>> import Signature
  >>> def fun(fred, lola):
  ...     pass
  ... 
  >>> s = Signature.Signature(fun)
  >>> s.full_arglist()
  ['fred', 'lola']

It's at <URI:http://www.sff.net/people/neelk/open-source/> -- let me
know what you think. The big limitation is that it won't work on C
builtins -- but all functions and methods written in Python should
work, including callable objects using a __call__ method.
