Builtn super() function. How to use it with multiple inheritance? And why should I use it at all?

That's not strictly true. It will call a method belonging to some
class in the mro of self, but that class is not necessarily in
the base list of the class mentioned in the super() call. It's
possible for a super() call to go "sideways" in the inheritance
graph.
