iter with stepsize

[Alan G Isaac]

If I have a sequence, I can get every other or every fifth
element by slicing. Is there an equivalent for iterators?

More specifically, I want every fifth line of a big file.
What is the most efficient way to get them?

Thanks,
Alan Isaac

Oh, of course.
I'm a bit embarrassed not to have thought
to look at itertools before posting.
Thanks!
