Tutorial writing views help

I am currently up to the "writing views" part of the tutorial and just wrote the polls/index.html template. I updated the view in polls/view.py as such:

from django.http import HttpResponse

from django.template import loader

from .models import Question

def index(request):

    latest_question_list = Question.objects.order_by('-pub_date')[:5]

    template = loader.get_template('polls/index.html')

    context = {

        'latest_question_list': latest_question_list,

    }

    return HttpResponse(template.render(context,request))

def detail(request,question_id):

    return HttpResponse("You're looking at question %s." % question_id)

def results(request,question_id):

    response = "You're looking at the results of question%s."

    return HttpResponse(response % question_id)

def vote(request,question_id):

    return HttpResponse("You're voting on question %s." % question_id)

I ran  $python manage.py check and the system identified no issues.

When I open the page 127.0.0.1:8000/polls/ I  get a blank page instead of a bulleted list of the questions I created.

Also I get the following error when I load 127.0.0.1:8000/polls/.

Page not found (404)

Request Method:	GET
Request URL:	http://127.0.0.1:8000/

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:

1. ^polls/
2. ^admin/

The empty path didn't match any of these.

mysite.urls

from django.conf.urls import url, include

from django.contrib import admin

urlpatterns = [

    url(r'^polls/', include('polls.urls')),

    url(r'^admin/', admin.site.urls),

]
