title: Finding max value in the second column of a nested list?
body: <p>I have a list like this:</p>
  <pre><code>alkaline_earth_values = [['beryllium',  4], 
                           ['magnesium', 12],
                           ['calcium',   20],
                           ['strontium', 38], 
                           ['barium',    56], 
                           ['radium',    88]]
  </code></pre>
  <p>If I simply use the <code>max(list)</code> method, it will return the answer <code>'strontium'</code>, which would be correct if I was trying to find the max <em>name</em>, however I'm trying to return the element whose integer is highest.</p>
