Alexander Belopolsky added the comment: Attached patch removes support for None from filter and itertools.ifilter. My objections for removing that from map do not apply because bool function can be used instead of None in filter achieving similar performance and better clarity.
None support was apparently removed from map in r60206. Remaining questions: 1. map(None,[]), filter(None,[]) and in fact map(anything,[]) still work. I don't think that needs to be fixed. 2. Should None support be removed from itertools.ifilterfalse? I would guess yes, unless it is going away. ---------- keywords: +patch Added file: http://bugs.python.org/file9551/filter.diff __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2186> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
