You've never had to deal with data where the first N items were special in some way? e.g. skipping over a header line in a file?
Of course I have. But never in the argument to enumerate(). [...]
and if that use case ever came up, passing a slice to enumerate() would be the appropriate thing to do.
While slices are wonderfully useful things, they aren't panaceas. They're not so useful with iterators, and they make a copy of the data, which can be problematic if there's a *lot* of it.
That's why we have itertools.islice(). -- --Guido van Rossum (home page: http://www.python.org/~guido/)
