At a system default level, in Debian, the command ‘python’ (if it is
installed) invokes the default Python 2 interpreter.

Based on existing discussions I am confident there will not be a
recommendation for a ‘python’ command to invoke anything except the
default Python 2 interpreter, until long after Debian ceases support for
Python 2 — and there is no current plan to drop Python 2 support in
Debian.

If you want a ‘python’ command at the system default level with
different behaviour from that today, that's going against
recommendations so I think you won't find a recommended way to have
different behaviour.

To have a command with custom behaviour, the recommendation is the
general one: put an executable file at ‘/usr/local/bin/python’ with
whatever behaviour you want.
