~~I can't get the flake8 linting to pass. What would be the acceptable way to format the long if statement in examples/guided.py?~~

Edit: I misunderstood the output of flake8, the problem was with the function call missing names for named parameters not the formatting of the long if statement. It is fixed now and the flake8 linting run was successful.

Updated this pull request to use locales instead of locale in preparation of pull request to add support for https://github.com/archlinux/archinstall/issues/1435.
