title: parsing json fields in python
body: <p>Is there a good tutorial on parsing json attributes in python? I would like to be able to parse the true value for "ok" field. As well as the index named "client_ind_1". I don't understand the python document coverage on this topic. If someone could explain or point me to a better resource, it would be awesome.</p>
  
  <p>My json string looks like the below:</p>
  
  <pre><code>{
      "ok": true,
      "_shards": {
          "total": 2,
          "successful": 1,
          "failed": 0
      },
      "indices": {
          "client_ind_2": {
              "index": {
                  "primary_size": "2.5mb",
                  "primary_size_in_bytes": 2710326,
                  "size": "2.5mb",
                  "size_in_bytes": 2710326
              }
          }
      }
  }
  </code></pre>
  
  <p>Thank you in advance.</p>
