title: Optimal method to find the max of sublist items within list
body: <p>I have a multidimensional list in the format:</p>
  
  <pre><code>list = [[1, 2, 3], [2, 4, 2], [0, 1, 1]]
  </code></pre>
  
  <p>How do I obtain the maximum value of the third value of all the sublists. In pseudo code:</p>
  
  <pre><code>max(list[0][2], list[1][2], list[2][2])
  </code></pre>
  
  <p>I know this can be done via iterating over the list and extracting the third value into a new list, then simply performing <code>max(list)</code>, but I'm wondering if this can be done using a lambda or list comprehension?</p>
