title: How can you create a timer for an input?
body: <p>For example:</p>
  <pre><code># 5 second response, if user doesn't do it in 5 seconds, then quit() 
  a = input('Stack Overflow is cool')
  
  if a == yes
      print('Harold882')
  else: 
      print('asdf')
  </code></pre>
  <h2>How can you do that, or just make a timer in general?</h2>
  <p>I also tried making different timers, but they didn't work.</p>
