Polymorphism in python

 Polymorphism:

• Poly means many and prism means form so polymorphism means many forms.
• It is used to perform a single action in different ways.
• For example,
• Action is drawn and it performance maybe draw a line or draw a circle.

Compile-time polymorphism:

• The runtime polymorphism is also called static polymorphism.
• It is the best example is method overriding.

Example program:

1. #method overriding or runtime polymorphism

   class Shape:

       result=0

       def area(self):

           print("\n\tCalculating area of Rectangle,Circle,Triangle .........")

   class Rectangle(Shape):

       def area(self):

           l=int(input("Enter length: "))

           w=int(input("Enter width: "))

           result=l*w; #area=length*width;

           print("Area of rectangle : ",result)

          

   class Circle(Shape):

       def area(self):

           r=float(input("Enter radius  of circle : "))

           result=3.14*r*r; #area=3.14*radius*radius;

           print("Area of circle : ",result)

    

   s=Shape()

   s.area()

   r=Rectangle()

   r.area()

   c=Circle()

   c.area()
