def __init__(self,x,y):
self.x=x
self.y=y
def __add__(self,other):
return test(self.x*other.x, self.y*other.y)
first=test(4,7)
second=test(5,6)
result=first+second
print(result.y)

if you use __add__ the method must return sum like
def __add__(self,other):
return self.x+other.x and not coma sepereted like you did
