Django doesn't render the url correctly. What's wrong?

Question

Django

Started learning Django and ran into a problem. When I open the site in a browser, it gives me the wrong URL. More precisely, at first everything is correct, " 127.0.0.1:8000 " opens, but I made navigation buttons there

<ul>
            <a href="{% url 'index' %}"><i class="fas fa-home"></i><li>Главная</li></a>
            <a href="{% url 'about' %}"><i class="fas fa-address-card"></i><li>Про нас</li></a>
            <a href=""><i class="fas fa-address-book"></i><li>Контакты</li></a>
        </ul>

And when I click on the "About Us" button, instead of " 127.0.0.1:8000/about " I get " 127.0.0.1:8000/about/about ", then when I click on "Home", I don't get thrown to " 127.0. 0.1:8000 ", but throws at " 127.0.0.1:8000/about "

Below is the code from the urls.py file

urlpatterns = [
    path('', views.index, name='index'),
    path('about', views.about, name='about'),
]

Code from main urls.py

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

from django.conf import settings
from django.conf.urls.static import static


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('index.urls')),
    path('about', include('index.urls')),
]  + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

views.py

from django.shortcuts import render
from django.http import HttpResponse


def index(request):
    return render(request, 'index/index.html')

def about(request):
    return render(request, 'index/about.html')

This is what it says in the source code in the browser

<ul>
            <a href="/about/"><i class="fas fa-home"></i><li>Главная</li></a>
            <a href="/about/about"><i class="fas fa-address-card"></i><li>Про нас</li></a>
            <a href=""><i class="fas fa-address-book"></i><li>Контакты</li></a>
        </ul>

Well, just in case, settings.py

Answer 1

As far as I understand, you indicated in the main urls file Correct on )
path('about/', include('app.urls.py'))
path('', include('app.urls.py')
