Question

What is polymorphism in PYTHON object-oriented programming?

Can I have a detailed and clear explanation please. Thank you :)

Answer 1

Polymorphism

1 . Polymorphism means that a code will behave differently at different conditions .

2 . It means that same function name is present and have different signatures being used for different purposes .

3 . Different signatures include same function name with different return types , different no of arguments related to type , count of numbers of arguments .

1 . Example of Polymorphism

#Function 1

def helper ( int a , int b )

return a+b

#Function 2

def helper ( float a , float b )

return a*b

#Function 3

def helper ( int a , float b )

return a / b

#Function 4

def helper ( float a , int b )

return a - b

#DRIVER CODE

print ( helper ( 3 , 4 ) ) // FUNCTION 1 CALLED

print ( helper ( 3.9 , 5,2 ) ) // FUNCTION 2 CALLED

print ( helper ( 3, 6.8 ) ) // FUNCTION 3 CALLED

print ( helper ( 3.2 , 8 ) )   // FUNCTION 4 CALLED

2 . POLYMORPHISM WITH INHERITANCE

I . When child class have same name methods which is present in Parent class .

II . Here , we re - implement the methods in child class .

III . Occurs if A ( ) function is present in Parent Class , and Child classes overrides that A() function in it's body .

IV . Also called Method Overriding .  

EXAMPLE :

class parent :

def intro ( ) :

print ( " In parent class " )

def help1 ( a ) :

print ( " Inside a " )

class child ( parent ) :

def intro ( ) :

print ( " In child class " )

#DRIVER CODE

obj1 = parent ( )  

obj2 = child ( )

obj1.intro ( ) // OUTPUT : " In parent class " .  

obj2. intro ( ) // OUTPUT : " In child class " .
