Description

Python 3.6 introduced formatted string literals, that are easy to use ​https://docs.python.org/3/reference/lexical_analysis.html#f-strings

But Django 2.0.2 does not recognize it when it tries to extract translations into PO file.

Demo:

# views.py
from django.utils.translation import ugettext_lazy as _

header = f'{_("Header")}'
header_old = '{}'.format(_("Header old"))

Run:

./manage.py makemessages -a

PO file would contain only "Header old".

I don't have much expertise about translations but is this a Python or xgettext issue rather than something Django can solve?

Yes, I guess the best we can do for now is documenting that current gettext limitation.
