Thanks, the locale.format() function indeed does what I need. However, my
understanding of it is that it uses the LC_NUMERIC locale info, rather
than the LC_MONETARY. For my purposes, this is certainly sufficient.

I'd like to use a class, but since this is part of a Zope application,
that's a little difficult (and overkill for this particular need).

It would be nice if we could have something like:
locale.format("%m",1000000,True,locale.LC_MONETARY)
though as is indicated in the strfmon docs, it wouldn't be quite so simple
(taking into account the different types of currency markers, padding,
spacing, etc).
