New submission from pavel-lexyr <pa...@lexyr.com>:
As described in the documentation, itertools.takewhile() returns all the elements until the first one that does not match the provided criterion. In case of a destructive iterator, or one with side effects, not yielding an element downstream may render takewhile() unsuitable for use. Proposed is itertools.takedowhile() - an alternate function that yields the first false element as well, and returns after. The behaviour is identical otherwise. ---------- messages: 397025 nosy: pavel-lexyr, rhettinger priority: normal severity: normal status: open title: itertools: takedowhile() type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44571> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
