_tkinter.TclError: invalid command name ".!canvas"

Hello, I don't understand what I did wrong in the code. IDLE wasn't even responding for a while.
Hopefully someone finds the error.
Thanks!

Try using global in function. See if that fixes the problem.

def somefunction():
    global a

---

Never Mine. It happening when you close game. It making a call after you destroy canvas.

Don't use time.sleep.
tkinter has there own. Every widget has .after.

def loop():
    # roughly 30 frames per second
    a.after(1000/30, loop) # timer_id = a.after(1000/30, loop, loop args)
