Barry A. Warsaw <barry@python.org> added the comment: The bug has been fixed upstream by replacing .format() with .format_string(). I'm not sure I understand why there are two different methods - .format() seems kind of pointless to me, but then I don't use the locale module enough to say what's useful. For Python 2.7 I think the only thing we can do is to update the docs so that the distinction and restrictions are clear. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue10379> _______________________________________
