Yes, I thought about this before I posted. I figured that, if I investigated further I would discover that there was a __main__ function that was being called. > > 1.

Quote below from http://docs.python.org/3/reference/datamodel.html: ======================================================================= Callable types These are the types to which the function call operation (see section Calls) can be applied: User-defined functions A user-defined function object is created by a function definition (see section Function definitions). It should be called with an argument list containing the same number of items as the function’s formal parameter list. Special attributes: Attribute Meaning __name__ The function’s name Writable ======================================================================= Perhaps I'm inferring too much from slightly-vague documentation, and my recent experience with objects that cannot be called? Or perhaps the information that I need to read is somewhere in the documentation other than where I have looked? Still puzzling over this... I can easily hack a solution as Terry suggested, but it's not elegant, and that kind of thing bugs me. -- https://mail.python.org/mailman/listinfo/python-list
