What is the correct way to set Python's locale on Windows?

It seems you're using Windows. The locale strings are different there. Take a more precise look at the doc:

locale.setlocale(locale.LC_ALL, 'de_DE') # use German locale; name might vary with platform

On Windows, I think it would be something like:

locale.setlocale(locale.LC_ALL, 'deu_deu')

You should not pass an explicit locale to setlocale, it is wrong. Let it find out from the environment. You have to pass it an empty string

import localelocale.setlocale(locale.LC_ALL, '')

This is the only correct way to use it, providing an example for the German locale:

import localelocale.setlocale(    category=locale.LC_ALL,    locale="German")  # Note: do not use "de_DE" as it doesn't work
