title: Multiple operations in a List Comprehension
body: <p>Say I do something like this:</p>
  
  <pre><code>vList=[1236745404]
  fList=[ "&lt;td&gt;{}&lt;/td&gt;".format ]
  [ f(x) for f, x in zip(fList, vList) ]
  </code></pre>
  
  <p>But now I want to convert the integer into a time string by feeding it into a multiple process stream.</p>
  
  <p>Pseudocode:</p>
  
  <pre><code>fList=[ "&lt;td&gt;{}&lt;/td&gt;".format(time.strftime("%a %H&amp;#58;%M %d %b %y", time.localtime())) ]
  [ f(x) for f, x in zip(fList, vList) ]
  </code></pre>
  
  <p>And what I want to see is:</p>
  
  <pre><code>['&lt;td&gt;Tue 22&amp;#58;23 10 Mar 09&lt;/td&gt;']
  </code></pre>
  
  <p>Is the List Comprehension variable input limited to one operation, or can the output be passed downstream?</p>
