If a file named "tkinter.py" is created and tkinter is imported and used within the file, the following exception is raised: "AttributeError: partially initialized module 'tkinter' has no attribute 'Tk' (most likely due to a circular import)"
I've spoken to multiple beginners who got stuck on this and just couldn't figure out what was happening. Just like the error message tells us, it's due to a "circular import". In other words, we're trying to import the very file that is doing the import. To make the message easier to understand, I propose that we change the message to something that mentions that the program is trying to import itself.
I think the following would be an option: "ImportError: partially initialized module 'tkinter' can't import itself"
I can't think of any reason to import itself in a way like this, but even if there is a valid reason, the error message could probably be improved. Of course, this applies to more than just tkinter.
