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

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

Look into how to set environment variables, specifically $DISPLAY

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.
