switch languages using pygettext in runtime

There is a small project:

[login to view URL]

It outputs:

'one, two, three'

If the line 13 _ = [login to view URL] is commented, then the output is translated to Russian:

'раз, два, три'.

Translation is performed using pygettext. Translations are stored in the locales folder.

There is a python module appendix.py. The module contains class Output. Output has a method additional_print().

Task: I need to switch between languages in __main__.py.

If i want to get Russian output , then _ = ru.gettext.

If i want to use English output, then _ = gettext.gettext.

I want to choose the language in __main__ only, and not in appendix.py.

No changes to the Output class should be done. The choise of the language should be somehow expanded to the [login to view URL] module. Language should not be passed as argument to the additional_print() funciton. Output class should stay in the module appendix.py. No dependency injection is possible.
