Well, you could get the previous stack level using traceback.extract_stack() and check the filename. But it sounds like what you actually have are two different methods -- one that is used by the superclass, and one that only the subclass knows about and uses. Why not implement it as such? -- http://mail.python.org/mailman/listinfo/python-list
