title: Input without stopping program
body: <p>I am trying to make a countdown timer that prints the time remaining, and when you input something, it prints what you inputted. My problem is I don't want to wait for the input, just keep running the timer. My incorrect code:</p>
  
  <pre><code>timer = 100
  while True:
      print(timer)
      timer -= 1
  
      if input('&gt; '):
          print('the output of input')
  </code></pre>
  
  <p>You could say I want to have the timer printing the time in the background.</p>
