thats ok, but how do i get it to group thousands with a , ?
and thats would mean i'd have to run everything through a formatter
before i displayed it :/ it'd be nicer if i could just select a

I think you're misusing locale. There is no guarantee that any
specific locale will have properties (like grouping) set to a known
value. Are you trying to format money? Then you need a special class
so that you can say:
d = Dollars(1000000.01)
print "You have %s in your account" % d
and get
You have $1,000,000.01 in your account.

thats exactly what i'm trying to do, only having to do that for all
my outputs is more work then i'd like :/
   

SUS has added numeric grouping
      For  some  numeric conversions a radix character (`decimal
      point') or thousands'  grouping  character  is  used.  The
      actual  character  used  depends on the LC_NUMERIC part of
      the locale. The POSIX locale uses `.' as radix  character,
      and does not have a grouping character.  Thus,
                  printf("%'.2f", 1234567.89);
      results   in   `1234567.89'   in   the  POSIX  locale,  in
      `1234567,89' in the nl_NL locale, and in `1.234.567,89' in
      the da_DK locale.
but they hasn't added monetary grouping. I don't think you'll
get monetary grouping anytime soon. Besides as far as I understood
your question, you *always* want grouping, right?
Actually I don't think a cryptic flag is better than an explicit
formatter. What do you think is more clear for a maintainer of your
code?
print "%'.2f" % amount
or
print "%s" % dollars(amount)


 

why is this a misuse of locale? it's exactly what locale is meant for
isn't it?
   

I just reacted to your words "select a proper locale" and "how do i get
it to group thousands with a ,". It's just not a good idea to select
a locale and expect the grouping character to be "," or expect
grouping,
see nl_NL locale example above.
 Serge.
 

i'm pretty sure english au uses thousands grouping with ,
i've managers to make this work, however it just isn't cross platform at 
all.
