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.
