title: Iterate over JSON objects in Python
body: <p>I get JSON from firebase (simplified):</p>
  
  <pre><code>logitems = {
  u'-K7w56QCnpYI': { u'Date': 1452707179865.0618, u'Message': 'messagetest1' },
  u'-K7w56safnpYI': { u'Date': 1452707179867.0618, u'Message': 'messagetest2' },
  u'-FSDFSDddsfsI': { u'Date': 1452707179868.0618, u'Message': 'messagetest3' },
  }
  </code></pre>
  
  <p>How can I iterate over the items (stored with keys instead in an array)? </p>
