You are right. I did not include the whole story in my last post.
This is the real code I used and so far it worked. I am still testing
it though. Toes and fingers crossed!
class Point(list):
def __init__(self, x, y, z = 1):
super(Point, self).__init__([x, y, z])
self.x = x
self.y = y
self.z = z
def __getattr__(self, name):
if name == 'x': return self[0]
if name == 'y': return self[1]
if name == 'z': return self[2]
def __setattr__(self, name, value):
if name == 'x': self[0] = value
if name == 'y': self[1] = value
if name == 'z': self[2] = value
Thanks for the correction.
