The list comprehension solution is slightly more approachable
(many are not familiar with the zip() function. I don't use zip on the
first go, if at all.)

The zip solution is succinct.

Also, by the virtue of being a built-in function zip() should be
faster than the second approach.

I wrote a script to test this hypothesis : http://dpaste.com/55994/
The zip() version is 100 times faster on average than the other solution.

#  avg time taken for ans1 :  0.0035585308075
#  avg time taken for ans2 :  0.306885209084
(averaged over 50 runs)
