Python Polymorphism: 3 Neat Examples

Poly means many, and morphism means forms. So polymorphism means many forms. Python supports object-oriented concepts like java. Below, you will find examples that explain the polymorphism of method/object/variable.

Polymorphism python

A rectangle appears in different shapes in different situations. Similarly polymorphism works. Here are three types of polymorphism in python VIZ: Method, Object, and Variable.

Polymorphism in Python real time examples

Method polymorphism

Here is the method with three arguments. The third argument value initialized with zero (c=0). I have supplied one time two arguments. The other time three arguments. For each, it gives an output. This way is called method polymorphism.

def meth1(a, b, c=0):
    return a + b + c

#Method polymorphism
print(meth1(1, 2))
print(meth1(1, 2, 3))

Method polymorphism

Object polymorphism

Here the same object gives two different results. Let us see how it works. Here, the class puppy assigns to two different objects with different inputs. The result is different – not the same. So it tells how object polymorphism works.

class puppy:
    
    def obj1(self, value):
        print(" My Value is : ", value)

#Object polymorphism
c1=puppy()
c2=puppy()

c1.obj1(400)
c2.obj1(300)

Output

 My Value is :  400
 My Value is :  300

Variable polymorphism

Here a class can take multiple variables(n). There is no fixed limit. And you will get a result different for each input.

class Demo:
    def mymul(self,*vars):
        mytotal=1
        for loop in vars:
            mytotal *= loop
            print("The Product of arguments is :",mytotal)

myobj=Demo()

myobj.mymul(10,20,30)
myobj.mymul(10,20)
myobj.mymul(10)
myobj.mymul()
myobj.mymul(10,20,30,40)

Output

For each input, you will get an output. The concept of this kind of polymorphism is called python variable polymorphism.

The Product of arguments is : 10
The Product of arguments is : 200
The Product of arguments is : 6000
The Product of arguments is : 10
The Product of arguments is : 200
The Product of arguments is : 10
The Product of arguments is : 10
The Product of arguments is : 200
The Product of arguments is : 6000
The Product of arguments is : 240000
