[Python-modules-team] Bug#902761: SyntaxError: Generator expression must be parenthesized with python3.7

[James Valleroy]

Package: python3-django
Version: 1:1.11.13-1
Severity: important
Tags: upstream

python3-django fails to configure when python3.7 is used.

I found this error when a CI build on Salsa failed:
https://salsa.debian.org/freedombox-team/plinth/-/jobs/28397

Setting up python3-django (1:1.11.13-1) ...
  File "/usr/lib/python3/dist-packages/django/contrib/admin/widgets.py", line 152

    ^
SyntaxError: Generator expression must be parenthesized

dpkg: error processing package python3-django (--configure):

The error has been fixed in Django 2.1:
