Create two public classes: Mammal and Bird. Each should inherit from the Animal class shown below.

For each new class, override the giveBirth method to produce the following output:

For the Mammal class, the method should return: "I give live birth"

For the Bird class, the method should return "I lay eggs"

class Animal: """This is an animal""" def giveBirth(self): """Return the birthing method""" return "I don't know how"
