Note that you can do this with properties. Something like (untested):

def getx(self): return self.position[0]
def gety(self): return self.position[1]
def setx(self, v): self.position[0] = v
def sety(self, v): self.position[1] = v
X = property(getx, setx, None, "X position")
Y = property(gety, sety, None, "Y position")
