Great job! I've not seen python-based keyboard firmware before, I'm impressed that it's fast enough to run something like a keyboard.
Without detracting from the code in the post, I recommend that anyone wanting to make and program their own keyboard should take a look at QMK, a widely supported keyboard firmware project that is FOSS: https://qmk.fm/
