Can't access Turtle Demo

[PythonAcolyte]

Greetings everyone, I am having this exact same issue and hoping that a solution was found.

Can anyone assist?

I'm running on a Mac and my version is 3.7. See below for my obviously poor attempts at doing this. I am very new to coding so please aim solutions at dummy level.
