'''
Polymorphism means one mane with many duties, the word polymorphism is made up of 2 words:
        1. Poly ---> Many
        2. Morphs ---> Forms
So in any OOP language it is possible to provide multiple meaning to the same funtion and this property is known as
    Polymorphism
Polymorphism is achieved by two ways:
    Function Overlaoding ---> Same class with multiple functions defined with the same name ---> not sopported by python
    Function Overriding --->  different inherited classes having mthods with same name

# Built in example of polymorphism

# 1. plus operator ---> can be used to addition of numbers as well as concatenation

a=20
b=30
print(a+b) # Addition of numbers(int, float, complex)

str1 = "Python"
str2 = 'Programming'
print(str1+" "+str2)

list1 = [1,3,4]
list2 = [5,6,7]
list3 = list1+list2
print(list3)
