Django: use yapf to adjust settings?

[hartym]

Following code kept for reference even if not working, but it would be amazing to be able to tune settings (like ensure that something is in INSTALLED_APPS). Maybe not achievable easily and safely, though.

    # Use yapf to adjust settings (for example, add some apps).
    @subscribe('medikit.feature.django.on_configure')
    def on_django_configure(self, event):
        original_source, newline, encoding = yapf_api.ReadFile('config/settings.py')
        print(original_source, newline, encoding)
        reformatted_code, encoding, has_change = yapf_api.FormatFile(
            'config/settings.py',
            in_place=True,
        )
        print(reformatted_code, encoding, has_change)
