An arduino working in conjunction with the Pi can fill in the gaps.  At
one time you could buy an arduino board that was also a Pi hat.  Python
on the Pi and C on the arduino seemed like a good idea to me.

Also there are microprocessor boards that can run MicroPython which does
offer some real-time functionality with a nice Python script front end.
