Frankly, I'd much rather fix the locale system and extend
the format syntax to override the default locale. Perhaps
something like
financial = Locale(group_sep=",", grouping=[3])
print("my number is {0:10n:financial}".format(1234567))
It's hard to think of a way of extending "%" format strings
to cope with this that won't look utterly horrid, though!
The problem with your example is that it magically looks for the locale
name "financial" in the current namespace.
True, to an extent. The counter-argument of "Is it so much
more magical than '{keyword}' looking up the object in the
parameter list" suggests a less magical approach would be to
make the locale a parameter itself:
print("my number is {0:10n:{1}}".format(1234567, financial)
Perhaps the name should be
registered somewhere like this:
locale.predefined["financial"] = Locale(group_sep=",", grouping=[3])
print("my number is {0:10n:financial}".format(1234567))
I'm not sure that I don't think that *more* magical than my
first stab! Regardless of the exact syntax, do you think
that being able to specify an overriding locale object (and
let's wave our hands over what one of those is too) is the
right approach?
