title: List Comprehension in 2.4
body: <p>Am i right to believe that you can only use else in list comprehensions within python 2.5 and higher ?</p>
  
  <p>i.e what would be the best way to achieve the following in 2.4 ?</p>
  
  <pre><code>print [x if x != "3" else "1" + "3" for x in ["1","2","3"]]
  </code></pre>
