How to find out which functions exist?

Ok, this makes sense. How can I do it inside the .py file I'm working
on? That is, consider this:

  class A:
    pass
  class B:
    pass
  import inspect
  print inspect.getmembers(<this file>, inspect.isclass) # how can I
express <this file> ?

Thanks again,
