ImportError: cannot import name 'url'
버전별로 차이
If you are using Django==1.11.0 then import should be as
from django.conf.urls import include
else if you are using Django==2.x, the import should be as,
from django.urls import include
UPDATE
Your code seems written in Django 2.x. So you have to update the django version and remove the line 16 from the code
