Python Polymorphism Explained WIth Examples

Polymorphism is using the same interface for various forms (in OOP) (data types).
Let's say we need to colour a shape; there are a variety of shapes to choose from (rectangle, square, circle). 

We could, however, apply the same technique to color any form. Polymorphism is the term for this notion.

class Penguin:

    def fly(self):

        print("Penguin can swim")

    def swim(self):

        print("Penguin can't fly")

class Penguin:

    def fly(self):

        print("Penguin can't swim")

    def swim(self):

        print("Penguin can fly")

# common interface

def flying_test(bird):

    bird.fly()

#instantiate objects

blu = Penguin()

peggy = Penguin()

# passing the object

flying_test(blu)

flying_test(peggy)
