1. I created a project, added main to it for the main page in views and about, there are no errors, but the text is not displayed nothing changes at startup, but on the main page it writes maybe I'm missing something? setting ![settings](https://i.sstatic.net/2hkmx.png]

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('main.urls'))
]

setting.py

    # Application definition

INSTALLED_APPS = [
    'main',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

def index(request):
    return HttpResponse("<h4>Hellow i'm main page</h4>")


def about(request):
    return HttpResponse('<h4>About as</h4>')

Urls.py in main app

from django.urls import path
from . import views
urlpatterns = [

Answer 1

You forgot the trailing '/'. Don't worry it happened to me plenty of times when i started learning Django. It drove me crazy not knowing where the error was. :D

Urls.py in the main app

path('about/', views.about)

Not

path('about', views.about)
