520    "When working with Python dictionaries, sometimes your 
       code has to deal with keys that may not be there; 
       depending on the situation, this is trickier than it 
       looks. In fact, your code may have a major bug in it right
       now! Learn the three different techniques for handling 
       missing dict keys, their different strengths, and 
       avoidable gotchas."--Resource description page.
