Sometimes you want a timer indepdent of the system clock, in case the system clock changes (e.g. ntpdate).

os.times() is the solution under Linux:

"Return a 5-tuple of floating point numbers indicating accumulated (processor or other) times, in seconds. The items are: user time, system time, children’s user time, children’s system time, and elapsed real time since a fixed point in the past, in that order. See the Unix manual page times(2) or the corresponding Windows Platform API documentation. On Windows, only the first two items are filled, the others are zero."

Under Windows, you could use time.clock(), which will return seconds since the process started. But on Linux the same function returns CPU usage.

Window One:
>>> import time

restarting the *program* on unknown exception is probably a better start
this would typically be implemented/configured by your init system
in upstart, it's just a matter of adding "respawn" to the config file
(there's options for saying how many times to try, with what sort of delay, etc)
systemd will have something as well
with an old-style shell-script based system, you'd probably want to look into the help "start-stop-daemon", which again has options for this sort of thing

if you want the process's exitcode, subprocess.call() returns that. If you want to execute something and raise an exception if it fails, subprocess.check_call() does that. If you want something more complicated, including a conversation with the process you're starting or simply not waiting for the process to end, subprocess.Popen is what you want.

import subprocess
r=subprocess.check_call(["ls"])
r=subprocess.call(["ls"])
r = subprocess.Popen(["ls"])
