idiom for list looping

[David Roberts]

To the best of my knowledge the second way is more pythonic - the
first is a little too reminiscent of C. A couple of notes:
- you don't need the parentheses around "i, e"
- if you were going to use the first way it's better to use xrange
instead of range for iteration
