I am following the official django tutorial https://docs.djangoproject.com/en/1.10/intro/tutorial04/
I am using Django 1.9.8 and I am now getting the following error
Latest tutorial (https://docs.djangoproject.com/en/2.0/intro/tutorial01/) uses Django 2.0, which supports Python 3.4 and later
Since I ran into this same issue I had to upgrade by python as well as django
sudo apt-get -y install python3-pip
pip3 install --upgrade django
to see your django version run following command -
python3 -c "import django; print(django.get_version())"
for me it says 2.0.1
To check python version run -
python3 --version
For me it is Python 3.5.2
