What is operator overloading..

Answer 1

Operator overloading allows you to use operators like +, -, *, etc. with custom classes.

Example:

http://code.sololearn.com/cbJlO8tA1Luv

class Complex:
re = 0
im = 0

def __init__(self, re=0, im=0):
self.re = re
self.im = im

def __str__(self):
return "({0},{1})".format(self.re, self.im)

def __add__(self, other):
re = self.re + other.re
im = self.im + other.im
return Complex(re, im)

def __mul__(self, other):
re = self.re * other.re - self.im * other.im
im = self.re * other.im + self.im * other.re
return Complex(re, im)

def __eq__(self, other):
return self.re == other.re and self.im == other.im

c1 = Complex(1, 2)
c2 = Complex(3, 4)
print(c1 + c2)
print(c1 * c2)
print(c1 == Complex(1, 2))

Answer 2

operator overloading is like operator performing multiple tasks eg + in Python can add numbers as well as concatenate strings. The result of such operator depends on it's argument😀

Answer 3

operator overloading means performing coustamised tasks using operators
eg + operator can be overloaded to perform addition of tuples also it can be used for subtraction after proper overloading
