IDLE is a GUI app running under Tkinters event loop.
I doubt if msvcrt works under Tkinter.
Try running your code in a DOS box.

Any solution that detects keyboard input will be
very sensitive to the operational environment.
Running in a GUI (any GUI) will cause keyboard
events that are handled by the GUI toolkit.
msvcrt is designed to catch keyboasrd events
within a DOS environment.

See the event handling page of my tutor for how
to detect keypresses within Tkinter.
