title: Sum the second value of each tuple in a list
body: <p>I have structure like this:</p>
  
  <pre><code>structure = [('a', 1), ('b', 3), ('c', 2)]
  </code></pre>
  
  <p>I would like to sum the integers (<code>1+3+2</code>) using <code>sum()</code> builtin method (in one line).</p>
  
  <p>Any ideas?</p>
