title: Reformat a simple string/list in Python
body: <p>Reformat a string, such as converting a list of authors like </p>
  
  <pre><code>"David Joyner, Ashok Goel, Nic Papin"
  </code></pre>
  
  <p>to </p>
  
  <pre><code>"Joyner, D., Goel, A., Papin, N."
  </code></pre>
  
  <p>Confused on where to go with this problem. I know it is simple and just uses methods such as <code>.split()</code> and <code>.strip()</code> but can't figure out what combination I need. Please help before I turn into Dobby banging my head on the wall. </p>
