title: Sort tuples based on second parameter
body: <p>I have a list of tuples that look something like this:</p>
  
  <pre><code>("Person 1",10)
  ("Person 2",8)
  ("Person 3",12)
  ("Person 4",20)
  </code></pre>
  
  <p>What I want produced, is the list sorted in ascending order, by the second value of the tuple. So L[0] should be <code>("Person 2", 8)</code> after sorting. </p>
  
  <p>How can I do this? Using Python 3.2.2 If that helps.</p>
