title: How to exit program using the enter key
body: <p>Michael Dawson says in his book <em>Python Programming</em> (Third Edition, page 14) that if I enter <code>input("\n\nPress the enter key to exit.")</code> when the user presses the Enter key the program will end. </p>
  
  <p>I have tried this several times and it doesn't happen. I have tried using Python 3.1 and 3.3. Help would be appreciated.</p>
