title: Iterating and printing JSON objects in Python
body: <p>I have a Google Spreadsheet that I'd like to get in Python, then process it through JSON. It's halfway working, and after looking through Stackoverflow for several hours, I think it's time to ask a question. </p>
  
  <p>For example, the format of the JSON file looks like this (from <a href="https://developers.google.com/gdata/docs/json" rel="nofollow">https://developers.google.com/gdata/docs/json</a>).</p>
  
  <pre><code>{

  </code></pre>
  
  <p>My Python code is as follows:</p>
  
  <pre><code>import requests, json
  r = requests.get('link-to-google-spreadsheet-json')
  j = r.json()
  </code></pre>
  
  <p>Testing the top-level hierarchy of the JSON file outputs as follows:</p>
  
  <pre><code>&gt;&gt;&gt; print j["version"]
  1.0
  </code></pre>
  
  <p>But iterating over the objects, like so: </p>
  
  <pre><code>for feed in j["feed"]:
      for entry in feed["entry"]:
          for title in entry["title"]:
              print title["$t"]
          print
      print
  </code></pre>
  
  <p>Gives me the following error: </p>
  
  <pre><code>Traceback (most recent call last):
  File "&lt;console&gt;", line 2, in &lt;module&gt;
  TypeError: string indices must be integers.
  </code></pre>
  
  <p>It sounds like it wants to print a single letter from the string, provided I give the index number. So how do I parse the JSON so that it correctly outputs what I want (e.g. feed -> entry -> title -> $t)?</p>
