title: Order of keys in dictionary
body: <p>I have a dictionary</p>
  
  <pre><code>{'a': 'first', 'b': 'second'}
  </code></pre>
  
  <p>However, I need the dictionary in a different order:</p>
  
  <pre><code>{'b': 'second', 'a': 'first'}
  </code></pre>
  
  <p>What is the best way to do this?</p>
