Chris has addressed your coding error. Within a function/method, you really should use a name for just one purpose, and especially if one of the purposes is global. But you have a different problem as well. You're describing an exception by retyping one of its lines, rather than using copy/paste of the whole thing. The actual error message could not have said "node", as there's no such name in the method. > > > > > def calcRoute(self): > self.openlist.append(Node(self.start, None, 0, 0)) > for Node in self.openlist: print Node.pos, Node.parent, Node.g, > Node.h, Node.f > -- DaveA
