Python Operator Overloading

The python operators work for built-in classes.but same operator behaves differently with different type.for example,the + operator will perform arithmetic addition on two numbers,merge two list and concatenate two string.this feature in python,that allows same operator to have different meaning according to the context is called operator overloading the following

Example

							
import math
 
class Circle:
 
    def __init__(self, radius):
        self.__radius = radius
 
    def setRadius(self, radius):
        self.__radius = radius
 
    def getRadius(self):
        return self.__radius
 
    def area(self):
        return math.pi * self.__radius ** 2
 
    def __add__(self, another_circle):
        return Circle( self.__radius + another_circle.__radius )
 
c1 = Circle(4)
print(c1.getRadius())
 
c2 = Circle(5)
print(c2.getRadius())
 
c3 = c1 + c2 # This became possible because we have overloaded + operator by adding a    method named __add__
print(c3.getRadius())
