title: Download JSON data and convert it to CSV using Python
body: <p>I'm currently using Yahoo Pipes which provides me with a JSON file from an URL.</p>
  
  <p>I would like to be able to fetch it and convert it into a CSV file, and I have no idea where to begin (I'm a complete beginner in Python).</p>
  
  <p>How can I fetch the JSON data from the URL?<br/>
  How can I transform it to CSV?</p>
  
  <p>Thank you</p>
