In Python 3.4 (don't know about other versions), list.__str__ doesn't exist; when you call str([1,2,3]) it calls object.__str__. The MRO for C is (C, list, User, object) so anything from list (eg append) takes precedence over anything from User, but anything list doesn't have will fall through to User before catching object.
