Calling the option python3 (not python) would give readers the same
message loud and clear in a simpler way, I would think.  Is there
any reasonable reason why we'd want to avoid saying python3?  It's
not like we are afraid of sending an message that we won't stay
working with python4 that is in the near horizon ;-), and as Arti
says, those who already live in Python3 world would know, when they
see either "python" or "python3", that is what they have anyway no?
