The following error message appears when I try to run the following code in cmd. (I use Djanjo version 1.11 and paython 3.7)

C:\Users\david\PAYTHON\SAIT1>py manage.py runserver

Hello David,

The current latest version of the Django 1.11 serie doesn't support Python 3.7[0] but

1.11.17, which is still unreleased[1], should per popular demand[2].

Until 1.11.17 is released I'd advise you either stick to Python 3.6 or upgrade to Django 2.0+.

Cheers,

Simon
