title: How to index into a dictionary?
body: <p>I have a Dictionary below:</p>
  
  <pre><code>colors = {
      "blue" : "5",
      "red" : "6",
      "yellow" : "8",
  }
  </code></pre>
  
  <p>How do I index the first entry in the dictionary?</p>
  
  <p><code>colors[0]</code> will return a <code>KeyError</code> for obvious reasons.</p>
