I am totally new to Django, and working through the following tutorial https://djangobook.com/views-urlconfs/

Ihavecreatddf the following view in views.py

from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello world")

 And then as per the tutorial updated urls.py as follows:

from django.conf.urls import url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hello/$', hello),
]

 When I try an browse http://127.0.0.1:8000/ I now no can no longer connect and the console shows the following error.

System check identified no issues (0 silenced).
