title: How to skip fields in a Json file with Python
body: <p>I'm trying to read a Json file to transform it into csv
  I looked on some stackoverflow questions and it helped me but I still have a little problem.
   There are fields that don't interest me and I don't know how to say to my script to skip these fields.</p>
  
  <p>Here is my code : </p>
  
  <pre><code>import csv
  import json
  
  x = """{
  "year": "2008",
  "title": "Movies",
  "items": [
  
  {
  "title": "The dark knight",
  "description": "A batman story"
  },
  
  {
  "title": "The Mummy: Tomb of the Dragon Emperor",
  "description": "A mummy story"
  
  },
  
  
  {
  "title": "Ironman",
  "description": "An Avengers story"
  
  }
  
  
  ]
  }"""
  
  
  x = json.loads(x)
  
  
  for key, value in x.items():
      print(key, value)
  </code></pre>
  
  <p>Of course I chose a very sample and short text to illustrate my example.</p>
  
  <p>When I run that script I get that : </p>
  
  <pre><code>(u'items', [{u'description': u'A batman story', u'title': u'The dark knight'}, {u'description': u'A mummy story', u'title': u'The Mummy: Tomb of the Dragon Emperor'}, {u'description': u'An Avengers story', u'title': u'Ironman'}]) (u'title', u'Movies') (u'year', u'2008')
  </code></pre>
  
  <p>And I would like to know how to display only the item's fields and to skip the fields "year" and "title" at the beggining.</p>
  
  <p>So, I would like to get the following output : </p>
  
  <pre><code>[{u'description': u'A batman story', u'title': u'The dark knight'}, {u'description': u'A mummy story', u'title': u'The Mummy: Tomb of the Dragon Emperor'}, {u'description': u'An Avengers story', u'title': u'Ironman'}])
  </code></pre>
  
  <p>I need to access only to these fields to write them in a csv file after. 
  So do you have an idea how I could do that ? </p>
  
  <p>Thank you very much in advance :) </p>
