SyntaxError: Generator expression must be parenthesized

I just installed django and after installing that I created a django project and was trying to run django server by command:

python manage.py runserver

After that I'am getting error as: SyntaxError: Generator expression must be parenthesized

TL; DR: Upgrade Django to version 1.11.17+ or 2.0+

This error is a known incompatibility related to Python issue #32012. Projects based on Django 1.11.16 and below will raise this exception when started with Python 3.7. A patch for this issue has been merged into Django 2.0 and 2.1 branches and cherry-picked later into Django 1.11.17.

Note: Python 3.7 is officially supported by Django 1.11.17 and above, including any 2.x branch.

Generator expression must be parenthesized

> Update Django version to 1.11.17

pip install django==1.11.17

Had same issue. This is how I changed to django version 2.0 and used python3

• $pip3 install django==2.0
• $python3 manage.py runserver
