Creating Snake game in Turtle

[Shadower]

Hello all,

I am creating a snake game with Python, in Turtle.
For this project, I am using this video: https://www.youtube.com/watch?v=rrOqlfMu...anThompson

The code I wrote is: https://pastebin.com/hAJhqu29

And the error I am getting is:
raise Terminator
turtle.Terminator


I tried looking online but I couldn't find help.

BTW- I am not using Pygame on purpose, since I am still a beginner and I want to learn the "basics".

Thanks in advance for your reply!
