Polymorphism is a ability of the method to appear in more than one form. Type of Polymorphism Compile-time and Run-time Polymorphism.
Python supports only Run-time Polymorphism. It is implemented by using
- Method/Function Overriding
- Base Class Object to Invoke the derived class Method
#Exmple - Runtime polymorphism in python class Shape: # define parent class def draw(self): print ('Drawing various shapes') class Rectangle(Shape): # define child class def draw(self): print ('Drawing Rectangles') class Circle(Shape): # define child class def draw(self): print ('Drawing Circles') # Creating the object of Rectangle class rect=Rectangle() # Creating the object of Shape class [Base class] sh=Shape() print('Python Runtime polymorphism Output') # calling the draw method from Shape class sh.draw() # Assigning the Reference of the Rectangle class to Shape class sh=rect sh.draw() # calls the draw method from the Rectangle class # Assigning the Reference of the Circle class to Shape class sh=cir sh.draw() # calls the draw function from the Circle class
