title: Dictionary not iterating in order
body: <p>Suppose I have a dictionary:</p>
  
  <pre><code>masterdict = {'28': ['28057', '28095', '28033'], '04': ['04025'], '24': ['24023']}
  </code></pre>
  
  <p>I simply want to iterate through each item in order. It was doing so before, and now seems to start at '24', then '28' and '04'. Why would this be happening?</p>
  
  <pre><code> for sFips, cFipsList in masterdict.iteritems():
      print sFips
      print cFipsList    
  </code></pre>
