Nick Coghlan added the comment: Serhiy, Hynek covered the issue with the status quo in the original proposal.The existing alternative are painful to try and decipher by comparison with the named function:
filterednext([0, None, False, [], (), 42]) vs next(filter(None, [0, None, False, [], (), 42])) filterednext([0, None, False, [], ()], default=42) vs next(filter(None, [0, None, False, [], (), 42]), 42) filterednext([1, 1, 3, 4, 5], key=lambda x: x % 2 == 0) vs next(filter(lambda x: x % 2 == 0, [1, 1, 3, 4, 5])) m = filterednext(regexp.match('abc') for regexp in [re1, re2]) vs m = next(filter(None, (regexp.match('abc') for regexp in [re1, re2]))) Hynek - the Python 3 filter is an iterator, so it works like the itertools.ifilter version in Python 2. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18652> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
