1. Basic urls

urls.py

from django.contrib import admin
from django.urls import path, include
from . import views
 
from django.conf import settings
from django.conf.urls.static import static
 
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', views.index, name='index'), # home / index / root
    path('blog/', include('blog.urls', namespace='blog'), name='blog'),
    # your paths are here ...
]
 
# To use media files you have to install - pip install Pillow
if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

first parameter is the url path.
second parameter is the function name from views.py file.
third parameter is the name of the page, that you can use in html file.

2. Dynamic urls/routs

It can be -
- int : 8
- str : page.html
- slug : hello-simple-post.html
Ex:

In urls.py :

urls.py

path('course/<int:courseID', views.course)
path('course/<str:courseName', views.course)
path('course/<slug:courseDetails', views.course)

In views.py :

views.py

def courseDetails(request, courseID):
    return HttpResponse(courseID)
