Let’s now look at a feature allowed by Python called multiple inheritance. As you may have guessed from the name, this is when a subclass inherits from more than one superclass. One form of multiple inheritance is when there are multiple levels of inheritance. This means a class inherits members from its superclass and its super-superclass.

class Animal: def __init__(self, name): self.name = name def say_hi(self): print("{} says, Hi!".format(self.name)) class Cat(Animal): pass class Angry_Cat(Cat): pass my_pet = Angry_Cat("Mr. Cranky") my_pet.say_hi() # Mr. Cranky says, Hi!

In the above example, Angry_Cat inherits from Cat and Cat inherits from Animal. Both Angry_Cat and Cat have access to the Animal class name attribute and .say_hi() method. Any feature added to Cat, Angry_Cat will also have access to.

Instructions

1.

Managers decide to start walking around more to let people know who is in charge.

Inside script.py:

  • Define a Manager class and have it inherit from the Admin class
  • Inside the Manager class, define a method say_id() that outputs that they are in charge.
2.

The Managers want to set a good example so they also let people know their ID and that they are an admin.

Inside the .say_id() method of Manager:

  • Call the Admin class .say_id() method
3.

Now test it out.

At the bottom of script.py:

  • Define a variable e4 and set it to an instance of the Manager class
  • Call the .say_id() method of the instance in e4

Now you will get output from all 3 classes.
