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.
