title: how to query using isodate in pymongo
body: <p>I have a mongodb query that works in the mongo shell:</p>
  
  <pre><code>db.collection.find({ created_at:  { $gte : ISODate("2015-03-01T00:00:00.000Z"), $lt : ISODate("2015-03-30T00:00:00.00Z") } })
  </code></pre>
  
  <p>I'm trying the following pymongo:</p>
  
  <pre><code>test_range = agents.coll.find({ "created_at" :  { "$gte" : "ISODate('2015-03-01T00:00:00.000Z')", "$lt" : "ISODate('2015-03-30T00:00:00.00Z')" } })
  </code></pre>
  
  <p>and I'm getting <code>SyntaxError: invalid syntax</code></p>
  
  <p>What the correct way to handle ISODate in pymongo query?</p>
