title: KeyError in Python 3.4
body: <p>I made a dictionary in python and so far there's nothing wrong when I print it like this:</p>
  
  <pre><code>print(video_game_company)
  </code></pre>
  
  <p>and I would get the expected result:</p>
  
  <pre><code>{('Street Fighter IV', 'Resident Evil 4'): 'Capcom', ('Crash Bandicoot', 'Uncharted', 'The Last of Us'): 'Naughty Dog', ('Prince of Persia: The Forgotten Sands', "Assassin's Creed", 'Watch Dogs'): 'Ubisoft'}
  </code></pre>
  
  <p>The indexes are as follows:</p>
  
  <ol>
  <li>Ubisoft</li>
  <li>Capcom</li>
  <li>Naughty Dog</li>
  </ol>
  
  <p>but when I type: </p>
  
  <pre><code>print("%s" % video_game_company["Capcom"])
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>KeyError: 'Capcom'
  </code></pre>
  
  <p>What am I doing wrong?</p>
