Does Turtle need Tkinter?

Question

So I am new to python and I am working through a turtle racer tutorial. I have copied the code exactly and the tutorial shows the code working at this point (though not complete). Mine does not. I installed tkinter on my first error that mentioned it, but now I get this error. I have modified the code a few different ways (included the commented out section using tkinter). What should I do to fix this error and continue on with my tutorial? This is the error I am getting and This is the incomplete code for the racer

Answer 1

It seems like it is looking for an environment variable that is not set.

Look into how to set environment variables, specifically $DISPLAY

Answer 2

Yes, it requires tkinter , it needs the Tk window for your output. You may refer to this post for clarification: here

Also, this post here provides a good explanation on how turtle operates in two modes: standalone and embedded.

Answer 3

Figured out the issue. I wasn't realizing the call back to the DISPLAY variable because I was too focused on the Tkinter problems and another user pointed out that part of the error.

I was coding on window's subsystem for linux which doesn't have a GUI. So I was just running code like I would on my actual linux machine without thinking. I ran the code on my linux machine that has a GUI and it worked without any tkinter code added in. It couldn't find the DISPLAY variable because there wasn't one on WSL.

Basically I just did something a bit dumb and realized my mistake. Thanks for the help, everyone!
