# class names should use CapWords convention (https://www.python.org/dev/peps/pep-0008/#naming-conventions)
class Vector:

    def __init__(self, *args):
        self.args = args

    # addition is normally a binary operation between self and other object
    def __add__(self, other):
        # other.args is the correct analog of self.args
        a = [arg1 + arg2 for arg1, arg2 in zip(self.args, other.args)]
        return self.__class__(*a)

    # __repr__ and __str__ must return string
    def __repr__(self):
        return self.__class__.__name__ + str(self.args)


v1 = Vector(1, 4, 8, 9)
v2 = Vector(5, 3, 2, 1)

print(v1)
print(v2)
print(v1 + v2)
print(v1 + v1 + v2 + v2)
