While going through django tutorial i found some errors when i tried to execute the python manage.py runserver.The error is attached below:

index.html:

{% if latest_question_list %}

  <ul>

  {% for question in latest_question_list %}

    <li><a href="/polls/{{ question.id }}/">{{

question.question_text }}</a></li>

  {% endfor %}

  </ul>

{% else %}

  <p>No polls are available.</p>

{% endif %}

admin.py:

from django.contrib import admin

from . models import Question

admin.site.register(Question)

views.py:

from django.shortcuts import get_object_or_404, render

from . models import Question

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)

def detail(request, question_id):

question = get_object_or_404(Question, pk=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)

detail.html:

<h1>{{ question.question_text }}</h1>

<ul>

{% for choice in question.choice_set.all %}

  <li>{{ choice.choice_text }}</li>

{% endfor %}

</ul>

from django.urls import path

from . import views

urlpatterns = [

# ex: /polls/

path('', views.index, name='index'),

]
