Python share CPU time?

[Yannick]

Thank you all for the detailled answers.

What I would like to achieve is something like:

# main loop
while True:
    for robot in robots:
        robot.start()
        robot.join(0.2) # wait 200ms
        if robot.is_active():
            robot.stop()
    # run all the game physics, pause, frame/rate, etc...

Unfortunately the stop() call doesn't exist in Python.

By using a generator I would make the assumption that every robot is
playing fair, and would yield often. But I cannot control this as
eventually robots would be coded by third parties.

Using Python scheduler would allow me to share time equally between
each robot, but then I would loose the ability to have a main thread
organizing everything.
