title: python boolean value to json string with quote
body: <p>all,</p>
  
  <p>I encounter an issue with a requirement. I know normally when change python boolean to json format, then gonna use the solution as below:</p>
  
  <pre><code>&gt;&gt;&gt;data = {'key1': True}
  &gt;&gt;&gt;data_json = json.dumps(data)
  &gt;&gt;&gt;print data_json
  {'key1': true}
  </code></pre>
  
  <p>The issue I have is that I need to have it as {'key1': 'true'}, string with quote ' or double quote ". Anyone knows is there any correct and simple way to do that? Thanks</p>
