Nick Coghlan <ncogh...@gmail.com> added the comment: OK, looking at the code I realised what you're trying to get at is the idea of reporting the differences between values in a series, such that:
x = list(accumulate(seq)) assert x == list(accumulate(differences(x))) I don't think the use cases are there to justify the addition (not every iterator we can think of should be a building block in itertools), but if such a thing were to be added, "differences" would convey the intention significantly better than the invented term "decumulate". ---------- nosy: +ncoghlan _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13252> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
