The class' MRO ("Method Resolution Order") determines in which
order attributes are looked up.
Either, you must order your base classes in such a way that the MRO
controlled lookup finds the methods you want to be used or
you must explicitely put a definition for those methods in your
derived class (it may have the form "overridden_method =
<BaseClass>.overridden_method").
The rules to determine the MRO are complex. The "inspect" module contains
a function ("get_mro") to show the MRO of a given class. Use it
to get your inheritance order right.
