inspect.isfunction returns True if the object is a *user-defined* function. For built-in functions, use inspect.isbuiltin. You might also be interested in the callable() function, which returns True if the object is any object that can be called. Cheers, Ian -- http://mail.python.org/mailman/listinfo/python-list
