overload operator python

class Vector:
  def __init__(self, x, y):
    self.x = x
    self.y = y
   
   def __add__(self, other):
      return Vector(self.x + other.x, self.y + other.y)

Python Overloading the + Operator

class Point:
    def __init__(self, x=0, y=0):
        self.x = x
        self.y = y

    def __str__(self):
        return "({0},{1})".format(self.x, self.y)

    def __add__(self, other):
        x = self.x + other.x
        y = self.y + other.y
        return Point(x, y)

python operator overloading deal with type

def __add__(self, other):
    if isinstance(other, self.__class__):
        return self.x + other.x
    elif isinstance(other, int):
        return self.x + other
    else:
        raise TypeError("unsupported operand type(s) for +: '{}' and '{}'").format(self.__class__, type(other))

Operator Overloading in Python

# Python program to show use of
# + operator for different purposes.
 
print(1 + 2)
 
# concatenate two strings
print("Geeks"+"For")
 
# Product two numbers
print(3 * 4)
 
# Repeat the String
print("Geeks"*4)
