how to dynamically instantiate an object inheriting from several classes?

I have a function that takes a reference to a class, and then instantiates that class (and then does several other things with the new instance). This is easy enough: item = cls(self, **itemArgs) where "cls" is the class reference, and itemArgs is obviously a set of keyword arguments f
