The command

who -Hu).


will give you idle time for each logged-in user

( H - print headers; u - list users )

and you could run this command via subprocess, then read and parse its
output.

Alternatively you could parse the same file(s) as who - I think it
reads /var/run/utmp - but that would be a lot more work, as it is a
binary file (run man utmp to see its format, use the struct module to
decode)

Best wishes,
