Somebody else emailed me another solution.

This is what he suggested:

class Point(list):
    def __init__(self,x,y):
        super(Point, self).__init__()
        self.x = x
        self.y = y

When I modified this to:

class Point(list):
    def __init__(self,x,y):
        super(Point, self).__init__([x, y])
        self.x = x
        self.y = y

It worked.
