locale.format is returning send("234,5") rather than send
("2,345") as I was expecting. Is this a bug?
The example is modified from the Tutorial 11.1 Output
Formatting

locale.format is implemented very "pragmatic". For example,
you can't do

locale.format('"1.%d."', 123)

("too many decimal points") though this should be supported.
This is because it first formats the string with the normal
"%" operation and then searches the whole string for decimal
points to substitute.

IMHO, format should first separate the % escapes from the
format string, then format the numbers accordingly, and then
use the % operation.

Berk,
I followed your advice using
'send("%s")' % locale.format("%d", data, grouping=True)
and solved my problem. Too bad there is no way to add your
advice to the Python documentation. I am putting the status
to remind, in case anybody (including me) wants to fix this
later.

Thanks.

The last comment set this issue to 'remind' in case someone wanted to fix it in the future...it's pretty much fixed now. format_string was added in 2.5, and in 2.6 format only accepts a string containing just a format code.
