I can only imagine jimbo1qaz intended "a more C-like way".  blech.

I **far** prefer The Python Way™.  The vast majority of the time,
I'm looping over some iterable where indices would only get in the
way of readability.  Tuple-unpacking the results of enumerate() is
an elegant way of getting both the items+indices on the seldom
occasion I need the index too (though I'm minorly miffed that
enumerate()'s starting-offset wasn't back-ported into earlier 2.x
versions and have had to code around it for 1-based indexing; either
extra "+1"s or whip up my own simple enumerate() generator).
