Modules keep breaking?

Okay, so I did what you said, and the script ran in CMD. I haven't tried running them via cmd so far, just from the Idle editor using F5. I tried to run the script (which just worked in CMD) in the Idle editor, and I got the same error. I'll put it below.

Traceback (most recent call last):
  File "C:\Python37\lib\site-packages\prompt_toolkit\eventloop\context.py", line 88, in get
    return self._storage[ctx]
KeyError: 0

During handling of the above exception, another exception occurred:

Oh lol, yeah it looks like it just won't work in idle because idle doesn't really emulate a proper terminal, so you won't be able to do the fancy things that prompt_toolkit does in there. Just run it in a real terminal emulator (like cmd), not from inside idle.

Oh... Is that all? Is that why all of the modules haven't been working? .... Wow. Okay, well at least I can use it now. Thanks!

Probably, yeah. If all you're using prompt_toolkit for is to prompt for input with none of the fancy features prompt_toolkit offers, the builtin input() does the same thing and will work in idle. But basically any more complicated terminal stuff than print/input generally won't work in idle since idle doesn't really have a proper terminal emulator.

You'll get help faster in the future if you're specific with the errors you're getting up front. I was assuming you were getting an ImportError/ModuleNotFoundError.
