[Tutor] Unbound Method Error

Because of the limited Python 3 support, I've decided to attempt to push my over 600 lines of code back to Python 2.6. Surprisingly, it worked well for the most part, except for the following section of code. crash = pygame.sprite.spritecollide(playerCar, computerSprites, False) if crash:

Disclaimer: I have no knowledge of PyGame. I think your original is a lack of checking types. You are calling BlueCar/GreenCar/Truck.collide regardless of the car type. If you pass a TruckSprite to BlueCarSprite.collide it makes sense (without knowledge of PyGame) that it would fail because it

Re: [Tutor] Assistance

b = + 2 is legal syntax, while b + = 2 is not. Why do you 'b += 2' is not legal syntax? It seems to work in python 2.x and 3.x. Is this deprecated or looked down upon? Is it better to use 'b = b + 2' ? For the +2, it did not even occur to me that it was referring to a positive number and not so

Hi Greg, You must use the class definition not an instance/object of it. If the class is called CarClass from some_lib_a.sub_lib_b import CarClass [...] isinstance(car, CarClass) OR import some_lib_a [...] isinstance(car, some_lib_a.sub_lib_b.CarClass) The following does NOT work: isinstance(c

Now I understand what I misunderstood. Well he imported Tkinter as tk, so I thought if it belonged to Tkinter it would be tk.after(), but the after was attached to the app, so it was in actuality app.after() . app inherits from the tk class (taking with it all its methods), so its a built in fun
