There is function os.sleep() and it seems that it works properly, but between two commands os.sleep(0.001) and os.sleep(0) there is a huge difference in time (second command executes much faster, you can check it by putting it in a loop) and there is no difference between os.sleep(0.001) and for example os.sleep(0.0000000001).. So is there any way to pause code avoiding os.sleep() and os.execute("sleep" time) that works in similar way? Because I need pause between 0.001 and 0
