Help adding a loop inside a loop

[deanhystad]

Check the next event each time through your while True loop.

If you run your outer loop frequently there is little difference between this:

events = normal_iterator() # One time through
while True:
    for next_event in events
        if time_to_execute_event(next_event):
            execute_event(next_event )
    # Do other stuff

And this

events = make_a_forever_iterator()  # Iterator that starts over when reaching end
while True:
    next_event = next(events)
    if time_to_execute_event(next_event):
        execute_event(next_event )
    # Do other stuff

I think the sched library is a better choice. Schedule events when you start your program or when an event gets added, and then forget about it. The event scheduler will run the event when it is scheduled to run.
