This is the winner:
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]
elif name == 'y':
return self[1]
elif name == 'z':
return self[2]
else:
return self.__dict__[name]
def __setattr__(self, name, value):
if name == 'x':
self[0] = value
elif name == 'y':
self[1] = value
elif name == 'z':
self[2] = value
else:
self.__dict__[name] = value
