execute function every x number of secods python

Question

I came across this thread when I was looking for a solution, but it doesn't quite do what I need it to:

What is the best way to repeatedly execute a function every x seconds in Python?

This actually "works" (or at least the first solution does) but it doesn't allow you to do it simultaneously along with the rest of the script.

Basically, I need to execute a function like this:

    def functionName():
        print "text"

I need this to execute every, say, 100 milliseconds. But I need this while loop to be looping simultaneously:

    while True:
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()

How would I go about this?

Thanks!

Did you take a look at [threading](http://docs.python.org/library/threading.html)? — bereal, Mar 27 '12 at 17:29

Shouldn't this work: http://www.pygame.org/docs/ref/time.html#pygame.time.set_timer

pygame.init()
pygame.time.set_timer(USEREVENT + 1, 100)
while True:
    for event in pygame.event.get():
        if event.type == USEREVENT + 1:
           functionName()
        if event.type == QUIT:
            pygame.quite()
            sys.exit()

Perhaps do you want to share a sample. – dani herrera Mar 27 '12 at 17:31
@danihp: I've added a sample copied from the comments in their documentation. – Bill Lynch Mar 27 '12 at 17:32
Yeah I saw that earlier and thought it didn't work. it actually does though. Damn this forum works well... – Max Hudson Mar 27 '12 at 17:34
I just started python and am dev'ing a game. it's a gorgeous language for intermediate programmers! – Max Hudson Mar 27 '12 at 17:38

This can be done by making a thread and using the wait() function so that it prints after every wait() function :) If you need help on threads, please look at the official documentation for help or look/ask for a different question on overflow. Cheers :)

You can probably install you function as a signal handler and use signal.setitimer. If you are on Unix, that is... Then there are threads and stuff.
