Hello.i wrote a ping pong game by using turtle with multithreading. The code shows no error in the editor but mutltyhreading isnot working probably and i believe i have so many mistakes.Can u make it better somehow pls. Thank you

import turtle

wn.title("Ping pong by Cagatay em")
wn.bgcolor("blue")
wn.setup(width=900, height=600)
wn.tracer(0)  #oyunu hizlandirir silersen cok yavaslar
