Python: Access Posix' locale database without setlocale()

Question

The setup is a Django based website on an Ubuntu server system with lots of useful information in /usr/share/i18n/locales.

The question: Can I access this pool of wisdom without using Python's locale.setlocale() afore?

The reason: The docs say, that it is

1. very expensive to call setlocale(), and

2. affects the whole application.

But in my case I have a, say, French site (Django handles setting the locale automatically), and I just want to display the name of January in the de_AT locale, or format a number like they do in Russia.

Answer 1

The magic library to achieve this is called Babel. Does what I want:

Before

import locale
setlocale(LC_ALL, 'de')
x = locale.format('%.2f', 123)
setlocale(LC_ALL, '')

After

from babel.numbers import format_decimal
x = format_decimal(123, format='#0.00', locale='de')

...and has a good Djang integration gratis.
