I can clearly understand what the above code is doing.  Doing this
as a list comprehension would be less readable for me (I'm not a 
heavy user of list comprehensions, yet.)  

Are you sure you really don't like the explicit, readable code 
above, and would prefer a more compressed, (admittedly explicit, 
I suppose), more cryptic version instead?  There are other
languages which could do the above in one tiny line, no doubt.
(No names. :)
