Check python3 (no need python2) version and pip3 version<\/p>\n

teddy@teddy:~$ python3 -V\r\nPython 3.5.2\r\nteddy@teddy:~$ python -V\r\nPython 2.7.12\r\nteddy@teddy:~$ pip3 -V\r\npip 9.0.1 from \/home\/teddy\/.local\/lib\/python3.5\/site-packages (python 3.5)<\/pre>\n
I need to upgrade pip with this command (must with sudo)<\/p>\n

create ‘polls’ app<\/p>\n
(django2.2) teddy@teddy:~\/Documents\/python\/django-apps\/django_app$ python3 manage.py startapp polls\r\n(django2.2) teddy@teddy:~\/Documents\/python\/django-apps\/django_app$ ls\r\ndb.sqlite3  django_app  manage.py  polls<\/pre>\n
That\u2019ll create a directory\u00a0polls, which is laid out like this:<\/p>\n
polls\/\r\n    __init__.py\r\n    admin.py\r\n    apps.py\r\n    migrations\/\r\n        __init__.py\r\n    models.py\r\n    tests.py\r\n    views.py<\/pre>\n
Write your first view
\nLet\u2019s write the first view. Open the file\u00a0polls\/views.py\u00a0and put the following Python code in it:<\/p>\n
from django.shortcuts import render\r\nfrom django.http import HttpResponse\r\n# Create your views here.\r\ndef index(request):\r\n    return HttpResponse(\"Hello world, You're at the polls index!\")\r\n<\/pre>\n
This is the simplest view possible in Django. To call the view, we need to map it to a URL – and for this we need a URLconf.<\/p>\n
To create a URLconf in the polls directory, create a file called urls.py. Then Open the file polls\/urls.py<\/p>\n
from django.urls import path\r\nfrom . import views\r\n\r\nurlpatterns = [\r\n    path('', views.index, name='index'),\r\n]\r\n<\/pre>\n
The next step is to point the root URLconf at the polls.urls module. In django_app\/urls.py, add an import for django.urls.include and insert an include() in the urlpatterns list, so you have:<\/p>\n
...\r\nfrom django.contrib import admin\r\nfrom django.urls import include, path\r\n\r\nurlpatterns = [\r\n    path('polls\/', include('polls.urls')),\r\n    path('admin\/', admin.site.urls),\r\n]<\/pre>\n
Then run the server<\/p>\n
(django2.2) teddy@teddy:~\/Documents\/python\/django-apps\/django_app$ python3 manage.py runserver<\/pre>\n
open: http:\/\/localhost:8000\/polls\/
\nNOTE: BUT I GOT AN ERROR IF I OPEN http:\/\/localhost:8000\/<\/p>\n
Page not found (404)\r\nRequest Method:\tGET\r\nRequest URL:\thttp:\/\/localhost:8000\/\r\nUsing the URLconf defined in django_app.urls, Django tried these URL patterns, in this order:\r\n\r\npolls\/\r\nadmin\/\r\nThe empty path didn't match any of these.\r\n\r\nYou're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.<\/pre>\n
