I knew it existed, but completely forgot about it.

Thanks also Peter.

Okay, so if I'm writing a wsgi app, and I want to format depending on
the choices of the currently logged in users, what would you recommend?

I can't do setlocale, since that would affect all users, and in a
mult-threaded environment that would be bad.

Does that mean the whole locale package is useless to all web-app builders?

from re import *

class editmoney(float):
def __init__(self,mymoney):
self.mymoney = mymoney
def __str__(self):
temp = "%.2f" % self.mymoney
profile = compile(r"(\d)(\d\d\d[.,])")
while 1:
temp, count = subn(profile,r"\1,\2",temp)
if not count: break
return temp

Blame it on the C guys ;)

I've seen

http://babel.edgewall.org/wiki/Documentation/intro.html
http://babel.edgewall.org/wiki/ApiDocs/babel.numbers
http://babel.edgewall.org/wiki/BabelFaq#WhatalternativesexistforPythonprojects

mentioned here but not yet tried it myself.

Here's a more elegant variant, using regexp lookahead:

def thous_format(integer_string):
"""
add comma thousands separator(s) to an integer-valued string
"""
return re.sub(r'(\d{3})(?=\d)', r'\1,', integer_string[::-1])[::-1]

I *thought* that I had found this on python-list on or about July 5, but
I didn't find the thread after a search through the archives.
