title: python, Json and string indices must be integers, not str
body: <p>I am using Python, and I sent a request to a URL and received a reply using httplib2. The reply I got was in JSon, how do I access a specific parameter. What I have at the moment is:</p>
  
  <pre><code>resp, content = parser.request(access_token_uri, method = 'POST', body = params, headers =     headers)
  raise Exception(content['access_token'])
  </code></pre>
  
  <p>and I get the error</p>
  
  <pre><code>string indices must be integers, not str
  </code></pre>
  
  <p>How do I do it?</p>
  
  <p>Thanks</p>
