Chapter 14. Multiple Inheritance

Multiple inheritance is where one class inherits from two or more other classes. Although Python (and, for example, C++) fully supports multiple inheritance, some languages—most notably, Java—don’t allow it. One problem is that multiple inheritance can lead to the same class being inherited more than once (e.g., if two of the base classes inherit from the same class), and this means that the version of a method that is called, if it is not in the subclass but is in two or more of the base classes (or their base classes, etc.), depends on the method resolution order, which potentially makes classes that use multiple inheritance somewhat fragile.

Multiple inheritance can generally be avoided by using single ...
