title: Json dump for key, pair in Python
body: <p>I have below file which is the result of a json dump. </p>
  
  <pre><code>"fdd6a102-359c-4527-8469-4ef01a9c0076": "[\n  {\n    \"resource_status\": \"CREATE_COMPLETE\", \n    \"resource_name\": \"i4_instance_internal_port\", \n    \"resource_type\": \"OS::Neutron::Port\", \n    \"physical_resource_id\": \"5db1d412-9a43-45c7-b72d-0dbe4eb16497\", \n    \"updated_time\": \"2017-07-14T09:00:44\"\n  }, \n  {\n    \"resource_status\": \"CREATE_COMPLETE\", \n    \"resource_name\": \"i3_instance\", \n    \"resource_type\": \"OS::Nova::Server\", \n    \"physical_resource_id\": \"50375d90-5b57-412e-afe3-fdddefbd2f41\", \n    \"updated_time\": \"2017-07-14T09:00:44\"\n  }, \n  {\n    \"resource_status\": \"CREATE_COMPLETE\", \n    \"resource_name\": \"i3_v1_instance_volume\", \n    \"resource_type\": \"OS::Cinder::Volume\", \n    \"physical_resource_id\": \"6750dc3d-e682-4a0c-a177-83a7252822fb\", \n    \"updated_time\": \"2017-07-14T09:00:44\"\n  }\n]\n"

  <p>This file is messed up I think. It is not in the right format. I researched on how to dump in json</p>
  
  <pre><code>def pp_another_json(myDict):
      import io
      try:
          to_unicode = unicode
      except NameError:

      # Write JSON file

          str_ = json.dumps(myDict,
                            indent=4, sort_keys=True,
                            ensure_ascii=False)
          outfile.write(to_unicode(str_))

      def getStackID(self):
          stacks = get_objects('stacks')

          for stack in stacks:

                  pp_another_json(myDict)
              except subprocess.CalledProcessError as e:
                  print("Error")

  <p>The output of openstack stack resource list  -f json comes in below format</p>
  
  <pre><code>[
    {
      "resource_status": "CREATE_COMPLETE",
      "resource_name": "i4_instance_internal_port",

  <p>Now my problems</p>
  
  <ol>
  <li>The json dump file doesn't really look like json to me. How can I get it to be in proper format</li>
  <li>The json dump file is a big one. so I have key as the ID and the value is the list inside which there is another dictionary.(I think so) How do I fetch data in such scenario?</li>
  <li>I need to check for example if 'resource_type' is OS::Cinder::Volume, how will I get it or else if I need to get the value of resource_type, how will I get it?  </li>
  </ol>
  
  <p>It will be helpful if someone can explain me my json file. Or if not, please direct me to the links that could help me understand nested dictionaries</p>
  
  <p>Edited : To fetch the value I did below and is giving me </p>

    <p>ValueError: too many values to unpack</p>

  <pre><code>    with open('data.json') as data_file:
          data_loaded = json.load(data_file)
          for key, value in data_loaded:
              print(data_loaded[key][0]['resource_status'])

  <p>data.json is below
