There is no general way for doing so. You need to consider the actual functionality of the methods involved. Consider a method spam() of class C that inherits from both A and B. To be completely general, you might have any of the following situations: C.spam() overloads A.spam() followed by B.spam() C.spam() overloads B.spam() followed by A.spam() C.spam() overloads A.spam() and overrides B.spam() C.spam() overloads B.spam() and overrides A.spam() C.spam() overrides both A.spam() and B.spam() (where I use "overload" to mean "modify the behaviour of", and "override" to mean "change the behaviour completely" -- basically, overloading will call the superclass' method, while overriding will not.) And (again, we're being completely general) whatever choice you make for C.spam() may not be valid for C.ham(), which could behave completely differently. The question you ask can only be answered in reference to a specific class with specific methods. There is no general principle, it depends entirely on the problem being solved. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
