New submission from Eric Smith <e...@trueblade.com>: I think the way leading zero padding is handled for int and float by format's 'n' code is a bug.
>>> import locale >>> locale.setlocale(locale.LC_ALL, 'en_US.UTF8') 'en_US.UTF8' >>> format(12345, '010n') '000012,345' >>> format(12345, '09n') '00012,345' >>> format(12345, '08n') '0012,345' >>> format(12345, '07n') '012,345' >>> format(12345, '06n') '12,345' When 'n' support was added to Decimal, leading zeros had commas in them: >>> from decimal import Decimal >>> format(Decimal(12345), '010n') '00,012,345' >>> format(Decimal(12345), '09n') '0,012,345' >>> format(Decimal(12345), '08n') '0,012,345' >>> format(Decimal(12345), '07n') '012,345' >>> format(Decimal(12345), '06n') '12,345' Decimal also has the same support for PEP 378's ',' modifier: >>> format(Decimal(12345), '010,') '00,012,345' >>> format(Decimal(12345), '09,') '0,012,345' >>> format(Decimal(12345), '08,') '0,012,345' >>> format(Decimal(12345), '07,') '012,345' >>> format(Decimal(12345), '06,') '12,345' >>> As I'm implementing PEP 378 for int and float, I'm going to make it work the same way that Decimal works. For consistency, and because I think the current behavior is not useful, I'd like to change float and int formatting with 'n' to match Decimal and PEP 378 for the ',' modifier. Since I consider this a bug, I'd like to consider backporting it to 2.6 and 3.0, if the changes aren't too intrusive. ---------- assignee: marketdickinson components: Interpreter Core messages: 83797 nosy: eric.smith, marketdickinson, rhettinger severity: normal status: open title: 'n' formatting for int and float handles leading zero padding poorly type: behavior versions: Python 2.6, Python 2.7, Python 3.0, Python 3.1 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5515> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
