Curses, emacs, vi, bash, CPython, nethack etc "solve the problem" by
setting the terminal mode. You can, too:
https://docs.python.org/3/library/termios.html
https://docs.python.org/3/library/tty.html
However, that only gives you access to the interpreted characters. For
example, you can't see when a [Shift] key has been pressed.

I don't consider that to be very low level. If you want to get to the
low level, open
/dev/input/by-id/*-event-kbd
