title: Parsing HTTP Response in Python
body: <p>I want to manipulate the information at <a href="http://www.quandl.com/api/v1/datasets/FRED/GDP.json">THIS</a> url.  I can successfully open it and read its contents.  But what I really want to do is throw out all the stuff I don't want, and to manipulate the stuff I want to keep.</p>
  
  <p>Is there a way to convert the string into a dict so I can iterate over it?  Or do I just have to parse it as is (str type)?</p>
  
  <pre><code>from urllib.request import urlopen
  
  url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'
  response = urlopen(url)
  
  print(response.read()) # returns string with info
  </code></pre>
