python operator overload code example

Example 1: 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)

Example 2: 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))
