Hi All, In Python 2, I can figure out whether I have a method or a function, and, more importantly, for an unbound method, I can figure out what class the method belongs to: >>> class MyClass(object): ... def method(self): pass ... >>> MyClass.method >>> MyClass.method.imclass <class '_main_.MyClass'> There doesn't appear to be any way in Python 3 to do this, which is a little surprising and frustrating... What am I missing here? You could always monkeypatch builtins.buildclass to add an attribute to every "unbound method" pointing to the class.

I would not reccomend that. build_class is very internal and it's contract may change between versions.
