title: Query Collection contents in Python client for Google Docs API
body: <p>How do I query the contents of a specific collection using the Python client for Google Docs API?
  This is how far I've come:</p>
  
  <pre><code>client = gdata.docs.service.DocsService()
  client.ClientLogin('myuser', 'mypassword')
  
  FOLDER_FEED1 = "/feeds/documents/private/full/-/folder"
  FOLDER_FEED2 = "/feeds/default/private/full/folder%3A"
  
  feed    = client.Query(uri=FOLDER_FEED1 + "?title=MyFolder&amp;title-exact=true")
  full_id = feed.entry[0].resourceId.text
  (res_type, res_id) = full_id.split(":")
  
  feed    = client.Query(uri=FOLDER_FEED2 + res_id + "/contents")
  
  for entry in feed.entry:.
      print entry.title.text
  </code></pre>
  
  <p>The first call to <code>Client.Query</code> succeeds and seems to provide a valid resource ID. The second call, however, returns:</p>
  
  <pre><code>{'status': 400, 'body': 'Invalid request URI', 'reason': 'Bad Request'}
  </code></pre>
  
  <ul>
  <li>How can I correct this to get it working?</li>
  </ul>
