Very nice. These solve a number of small but real problems and it looks like a great utility package!

I think the docs of iterutils.split() vs. iterutils.split_iter() might be a little off.

They both claim to return lists but split_iter() says if you want lists, see split(). Without having installed the package yet, my guess is split_iter() returns an iterator. Either way, the docs are contradictory.

Thanks for this!
