Inheritance

Question

What is operator overloading with methods? Illustrate with the help of an example using a python code.

Solution

Operator overloading is an ability to use an operator in more than one form.
Examples:
In the following example operator + is used for finding the sum of two integers:
a = 7
b = 5
print(a+b) #gives the output: 12

Whereas in the next example, shown below the same + operator is used to add two strings:
a = 'Indian '
b = 'Government'
print(a+b) #gives the output: Indian Government
