Chapter 1: Python 3.7 and Django - "SyntaxError: Generator expression must be..." about book-tdd-web-dev-python HOT 10 CLOSED

To fix this, edit this file: [virtual env directory]/lib/python3.7/site-packages/django/contrib/admin/widgets.py

delete the following lines [150-153]

        related_url += '?' + '&'.join(
                    '%s=%s' % (k, v) for k, v in params.items(),
                )

and add this in place:

related_url += '?' + '&'.join('%s=%s' % (k, v) for k, v in params.items())

Fixed by installing a recent version of Django instead. https://www.djangoproject.com/download/

just to re-iterate: i recommend you use the latest version of django 1.11 that exists, and as far as i know it is compatible with python 3.7. if you upgrade to django 3 you will have to spend time figuring out which problems are real problems and which are just due to django version differences.

Thanks, l also have that problem and was solved with your suggestion. l hope that there are no more problems using python3.7 and django in virtualenv

I thought the latest point release of django 1.11 actually fixed this anyway?
