title: print output in 1 line separated by commas
body: <p>I have 1 list:</p>
  
  <pre><code>mylist=[John, Stefan, Bjarke, Eric, Weirdo]
  </code></pre>
  
  <p>I want to print the whole thing in one line separated by commas using a for loop, like:</p>
  
  <pre><code>for x in mylist:
      print x
  </code></pre>
  
  <p>How do I do this?</p>
