title: pprint(): how to use double quotes to display strings?
body: <p>If I print a dictionary using <a href="http://docs.python.org/2/library/pprint.html"><code>pprint</code></a>, it always wraps strings around single quotes (<code>'</code>):</p>
  
  <pre><code>&gt;&gt;&gt; from pprint import pprint
  &gt;&gt;&gt; pprint({'AAA': 1, 'BBB': 2, 'CCC': 3})
  {'AAA': 1, 'BBB': 2, 'CCC': 3}
  </code></pre>
  
  <p>Is there any way to tell <code>pprint</code> to use double quotes (<code>"</code>) instead? I would like to have the following behaviour:</p>
  
  <pre><code>&gt;&gt;&gt; from pprint import pprint
  &gt;&gt;&gt; pprint({'AAA': 1, 'BBB': 2, 'CCC': 3})
  {"AAA": 1, "BBB": 2, "CCC": 3}
  </code></pre>
