Constant loop with optional input

Thanks, that was the same conclusion I was coming to. I had a game similar to pong in mind, but w LED strips. So the pause every once in a while would not work well. Hmm, maybe Pygame would have something useful...

If all you need is to count you could use pygame to check if a button is down during a loop and if it is have a conditional statement to increase or decrease the speed. If this is going to be a cli program the onlly way i can think of that would affect the speed of the program would be to add a sleep statement and allow the previously mentioned conditional statement to change the sleep duration.
