Question

how can you add two values using __add__ function

(1,2)+(2,3) = (3,5)



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

is this the way to think?
What is the probable error!!

Answer 1

That’s close, except you need to return NotImplemented if it’s not a Point:

def __add__(self, other):
    if not isinstance(other, Point):
        return NotImplemented
    return Point(self.x + other.x, self.y + other.y)
