Summary: UNIX-locale and repr()

Initial Comment:
Hi, 
 
please look at this code snippet: 
 
#!/usr/bin/python 
import sys 
import os 
import random 
import locale 
locale.setlocale(locale.LC_ALL, 'de_DE@euro') 
dp = locale.localeconv().get('decimal_point', '.') 
# print "--->",locale.localeconv() 
print "--->",dp 
a = random.random() 
b = repr(a) 
print b 
 
with this output : 
 
---> , 
0.24851180874790457 
 
I expect that the output of b must be "0,24851180874790457" 
with a "," as a decimal point corresponding to the locale. 
But for floating point numbers repr() always delivers the "." 
as decimal point for the german locale. 
 
The real problem occurs in the email package 
(http://mimelib.sourceforge.net/) in the method : 
 
def _make_boundary(text=None): 
     # Craft a random boundary.  If text is given, ensure that the 
chosen 
     # boundary doesn't appear in the text. 
     dp = locale.localeconv().get('decimal_point', '.') 
     boundary = ('=' * 15) + repr(random.random()).split(dp)[1] + 
'==' 
 
for the german locale (error 'listindex out of range') on 
repr(random.random()).split(dp)[1]. 
 
Kind regards 
Jörg Linnenkohl

This is a known issue.  Python requires that LC_NUMERIC for 
locale settings *always* be set to the "C" locale.  This is so that 
numeric values stored in .pyc files can be converted with no issue 
from their string representation to the proper Python object.  This 
was all recently discussed on python-dev; see the python-dev 
Summary for July 2003 when it comes out (by the end of the 
week) for a summary of the issue and discussion.

So the code in the email package is wrong for thinking repr will 
return anything that uses something other than a period for a 
decimal point.  Since this is a 2.1.x issue (changed in 2.2.x 
branch) I am lowering the priority on this.  Or should this just be 
closed?
