No it cannot be done. This is because a translation can reorder
the parts of the string is drastic ways that f'strings' does not allow for.

You need to use this style:

	_('This %(arg1)s and %(arg2)s') % {'arg1': value_arg1, 'arg2': value_arg2}

or
	_('This {arg1} and {arg2}').format(arg1=value_args, arg2=values_arg2)

A translator would be free to swap arg1 and arg2 order in a translation.

See https://docs.python.org/3/library/gettext.html for more details.
And https://www.mattlayman.com/blog/2015/i18n/ looks useful as well.

Then you can use use the I18N gettext tools to make a .pot and .po files.
