Multiple Inheritance Conceptual Question

Good questions:

Question 1 - Why ?

I could not find the specific case where the version of Python would matter in the MRO unless you go back to an very old version of Python 2, So, I would say the comment is moot if you're using a modern 2.7+, 3.5+ version of Python.

Please note that with Character as the first class in the inheritance list and the Character.__init__ does not have a super call, neither Agile.__init__ or Sneaky.__init__ would be executed. The setting of the self.sneaky attribute is happening in the Character loop using setattr.

Question 2 - Why do have super().__init__ in sneaky and agile classes if the only parent class they have is Object ?

Any super call become effectives when there are multiple parent classes are inherited from. A super within` a parent class says "if I don't have a parent, then run this same method contained *in the next parent in the inherited list". The Agile.super calls Sneaky. The Sneaky.super calls Character.

Question 3 - What benefit do we get in making character class as final class ?

By making Character the final class, it allows that class to be the default structure of the defined class Thief. Any supplemental features added to augment the Thief class can then be added before Character. In terms of design, Character is the "base class" of Thief and the classes Agile and Sneaky can be thought of as "add in features".

Post back if you wish more clarification. Good luck!!
