Your function index(request) inside polls/views.py is badly written (you have three function returns). Seems you are following the tutorial but not removing the previous examples:

def index(request):
    latest_question_list = Question.objects.order_by('-pub_date')[:5]
    context = {'latest_question_list': latest_question_list}
    return render(request, 'polls/index.html', context)

Sure:

from django.http import HttpResponse

from .models import Question


def index(request):
    latest_question_list = Question.objects.order_by('-pub_date')[:5]
    output = ', '.join([q.question_text for q in latest_question_list])
    return HttpResponse(output)
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)

As a matter of advice, please use a fixed-width font when pasting code, because Python is indented with spaces and using any other type of font makes reading your mail difficult :)

I think the root cause of the errors was due to an incorrect settings -
but Fidel is right that your views.py wasn't great either.
