title: How to extract specific fields and values from a JSON with python?
body: <p>I am iterating a JSON and I want to extract the following fields from this object:</p>
  
  <ol>
  <li>Id,  </li>
  <li>Open_date</li>
  <li>User </li>
  <li>Ticket_status</li>
  <li>End_date </li>
  </ol>
  
  <p>The data structure that I have is like the following :</p>
  
  <pre><code>filtered_data = 
  [{'id': 1021972, 'Aging_Deferred_Transferred': '', 'Aging_Open_Issue': '0.94', 
  'Aging_Un_investigated_Issue': '0.94', 'User': 'John P.', 'ModifiedOn': '2017-09-04 21:29:59', 
  'Open_date':'2017-08-04 01:34:18','End_date':'2017-09-05 00:29:01',
  'Ticket_status':'Transferred'},{'id': 1036722, 'Aging_Deferred_Transferred': '', 'Aging_Open_Issue': '0.12', 
  'Aging_Un_investigated_Issue': '0.01', 'User': 'John P.', 'ModifiedOn': '2017-09-04 21:29:59', 
  'Open_date':'2017-09-01 00:34:18','End_date':'',
  'Ticket_status':'Researching'},{'id': 1015621, 'Aging_Deferred_Transferred': '', 'Aging_Open_Issue': '0.99', 
  'Aging_Un_investigated_Issue': '0.11', 'User': 'John D.', 'ModifiedOn': '2017-06-05 12:19:59', 
  'Open_date':'2017-01-01 00:00:18','End_date':'2017-09-01 20:20:57',
  'Ticket_status':'Closed'}]
  </code></pre>
  
  <p>I want to return a data structure such as a Dictionary (if you think there is a better a data structure for achieving my goal please mention it) as the following:</p>
  
  <pre><code>dict_user_john_p = {'ID':1021972,'Open_date':'2017-08-04 01:34:18','Ticket_status':'Transferred','End_date':'2017-09-05 00:29:01',
  'ID':1036722,'Open_date':'2017-09-01 00:34:18','Ticket_status':'Researching','End_date':''}
  
  dict_user_john_D = {'ID':1015621,...,'End_date':'1015621'}
  </code></pre>
  
  <p>How can I extract the mentioned specific fields and return them as another data structure (dictionary)?</p>
