Python ... ugly but efficient.

Lisp ... wonderful but ... yeah, to some extent.

Now do it in Lisp and let's compare. But the biggest
difference (aside for beauty) will be the time spent writing
the code - an expert lisper and beginner/medium level Python
programmer should spend a comparable amount of time :) - not
time in execution.

Then I include googling solutions ...

The true expert does everything very rapidly. But who is
a Lisp expert? I can think of one person on this list and it
sure ain't me :)
