I had a thought about locale-specific formatting.
Currently, when we want to do locale-specific formatting we use the locale module like this:
locale.format("%d", 12345, grouping=False) '12345' locale.format("%d", 12345, grouping=True) '12,345'
This makes it harder to use more than one locale at a time, or one which is different from the default.
My thought was that we could specify a locale in the format specification mini-language and the parameter list of str.format, something like this:
loc = locale.getlocale() "{0:@1}".format(12345, loc) '12345' "{0:, at 1}".format(12345, loc) '12,345' ... "UK says {value:,.1f at uk} and France says {value:,.1f at france}".format(value=12345, uk=uk_loc, france=france_loc) 'UK says 1,234.5 and France says 1 234,5'
