title: Print index number of dictionary?
body: <p>I'm trying to pull out strictly the index number from the following dictionary:</p>
  
  <pre><code>data = {0: {'GAME_ID': '0021600457', 'TEAM_ID': 1610612744}, 1: {'GAME_ID': 
  '0021600457', 'TEAM_ID': 1610612744}, 2: {'GAME_ID': '0021600457', 'TEAM_ID': 
  1610612744}
  </code></pre>
  
  <p>I'd like to be able to do something like</p>
  
  <pre><code>print(data[x])
  </code></pre>
  
  <p>And have it return:</p>
  
  <pre><code>0
  </code></pre>
  
  <p>I'm sure this is something simple that I'm overlooking?</p>
