title: Extract data from JSON in python
body: <p>Can I access link inside <code>next</code> from the below <code>Json</code> data? I am doing in this way </p>
  
  <pre><code>data = json.loads(html.decode('utf-8'))
  for i in data['comments']:
          for h in i['paging']:
              print(h)
  {
  </code></pre>
  
  <p>Because <code>comments</code> is a main object. Inside the <code>comments</code> there are three sub objects <code>data</code> , <code>paging</code> and <code>summary</code>. The above code is doing the same , inside <code>comments</code>, because of <code>paging</code> is an object of multiple other objects, in the loop and print that. It is giving the error</p>

    <p>for h in i['paging']:
    TypeError: string indices must be integers </p>
