Hi, I'm at https://docs.python.org/3.8/library/tkinter.html#:~:text=Running%20python%20... . There's a helpful paragraph that explains how to check/confirm that tkinter is present. I clearly don't have it. My suggestion is to add something to guide the unfortunate to where/how to get it! I arrived at that page via google - 'python can't find tkinter' I'm running ubuntu and python3. My knowledge of managing python is limited but I have tried 'pip install tkinter' and that hasn't worked. It said success but python didn't find tkinter. I have since tried 'sudo apt install python3.8-tk' and that said: Note, selecting 'python3-tk' instead of 'python3.8-tk' So, I now have a working tkinter. You could make it a bit easier!
