title: python firebase realtime listener
body: <p>Hi there I'm new in python.
  I would like to implement the listener on my Firebase DB.
  When I change one or more parameters on the DB my Python code have to do something.
  How can I do it?
  Thank a lot</p>
  
  <p>my db is like simple list of data from 001 to 200: </p>
  
  <pre><code>"remote-controller"
  001 -&gt; 000
  002 -&gt; 020
  003 -&gt; 230
  </code></pre>
  
  <p>my code is:</p>
  
  <pre><code>from firebase import firebase
  firebase = firebase.FirebaseApplication('https://remote-controller.firebaseio.com/', None)
  result = firebase.get('003', None)
  print result
  </code></pre>
