But not on OS X. It raises TestSkipped saying how locale support is so minimal that it isn't worth testing. Yeah, I'm going remove that and test it out...that message may be bogus at this point - it was put there a year and a half ago by Jack, and I'm reasonably sure that no one's tested it since (and I don't believe it anyhow - it's more like Python's support is bad - MacOS X's support for locale is pretty good).

MacOSX's support for locale was abysmal up to 10.2, a trait which it inherited from FreeBSD. It is much better under 10.3 (but still completely separate from the MacOSX native way to specify currency signs and what have you).

But it seems the C library doesn't use the locale info, here's the output from test_locale (from cvs head, on 10.3.4):

'%f' % 1024 =? '1,024.000000' ... no '%f' % 1024 == '1024.000000' != '1,024.000000' '%f' % 102 =? '102.000000' ... yes '%f' % -42 =? '-42.000000' ... yes '%+f' % -42 =? '-42.000000' ... yes '%20.f' % -42 =? ' -42' ... yes '%+10.f' % -4200 =? ' -4,200' ... no '%+10.f' % -4200 == ' -4200' != ' -4,200' '%-10.f' % 4200 =? '4,200 ' ... no '%-10.f' % 4200 == '4200 ' != '4,200 '
