Different people mean different things by "real time", as you pointed
out.  For your meaning of "real time", I agree with you.  But for
another meaning of "real time" --- "guaranteed worst-case response
time" --- I don't think Python is suitable, because a programmer
cannot correctly calculate a worst-case response time for any but the
smallest Python programs.
