Polymorphism

In Python, polymorphism refers to the ability to use a shared interface for several data types.

Start IDLE.

Navigate to the File menu and click New Window.

Type the following line of code:

class Tilapia:

def swim(self):

print("Tilapia can swim")

def fly(self):

print("Tilapia cannot fly")

class Shark:

def jump(self):

print("Shark can't fly")

def swim(self):

print("Shark can swim")

def jumping_test(fish):

fish.jump()

bonny = Tilapia()

biggy = Shark()

jumping_test(bonny)

jumping_test(biggy)

Explanation

The program above has defined two classes Tilapia and Shark all of which share the method jump() even though they have different functions.

By creating common interface jumping_test() we allowed polymorphism in the program above. We then passed objects bonny and biggy in the jumping_test() function.

Work to do

In a doctor consultation room suggest the class and objects in a programming context.
