class Coordinate(object):
    def __init__(self,x,y):
        self.x = x
        self.y = y
    def __str__(self):
        return f'({self.x}, {self.y})'
    def __add__(self,other):
        return Coordinate(self.x+other.x,self.y+other.y)


x1,y1 = list(map(int,input().split()))
x2,y2 = list(map(int,input().split()))
c1 = Coordinate(x1,y1)
c2 = Coordinate(x2,y2)
print(c1+c2)

上一个的思路不太好，还是在用java的思路，没转换到python上来
