The __mro__ descriptor does what you want. Example: >>> class A(object): ... pass ... >>> class B(object): ... pass ... >>> class C(A, B): ... pass ... >>> C.__mro__ (<class '__main__.C'>, <class '__main__.A'>, <class '__main__.B'>, <type 'object'>) See: http://www.python.org/download/releases/2.2.3/descrintro/ and http://www.python.org/download/releases/2.3/mro/ for details.
