title: How to get minimum item from a dict of lists?
body: <p>My dictionary looks like this:</p>
  
  <pre><code>Key:                List:
  AB                   [A, B, 32]
  AC                   [A, C, 20]
  AD                   [A, D, 18]
  </code></pre>
  
  <p>I want to get the key that has the minimum value in the third location on the list. So, <code>AD</code> is what I want outputted.</p>
  
  <p>The code I am using is:</p>
  
  <pre><code>print min(dict.keys(), key=lambda x: x[2])
  </code></pre>
