How to make a countdown timer that runs in the background, which terminates the program when it runs out?
<p>I am making a Who Wants to be a Millionare game in Python using graphics. I want the user to get 45 seconds per question to answer it. However, whenever I put a timer in my code it waits for 45 seconds first, <em>then</em> lets the user answer, instead of running in the background and letting the user answer at the same time.</p>
