The purpose of islice is to slice arbitrary iterables as opposed to just sequences. But this function requires a reentrant iterable anyway and returns garbage if you pass it an iterator, so there's really no reason for it here. The version using slice notation on the other hand will raise a TypeError if you pass it an iterator or anything else that can't be sliced, which is preferable to silently returning incorrect results.
