Never do this. It's called a "busy-wait", and not only does it saturate your Python thread, it also saturates your entire system - this is going to keep one CPU core permanently busy going "are we there yet? are we there yet?" about the one-second delay. Instead, use time.sleep(), which will delay your thread by one second, allowing other threads to run. Better still, think about your code in terms of events. Most GUI libraries these days are built around an event-driven model, and the notion of "make this event happen 1 second from now" or "10 seconds from now" is a very common one.
