ModuleNotFoundError: No module named 'To_do.todos' - DJANGO - django

Question

So I just started learning django, and I was learning from this youtube video: https://www.youtube.com/watch?v=Nnoxz9JGdLU
So here is my directory map:
To_do
+To_do
+_pycache_
+_init_.py
+asgi.py
+settings.py
+urls.py
+wsgi.py
+todos
+_pycache_
+migrations
+_init_.py
+admin.py
+apps.py
+models.py
+tests.py
+urls.py
+views.py
+db.sqlite3
+manage.py
code of To_do/To_do/urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('todos/', include('todos.urls'))
]
code of To_do/todos/urls.py
from django.urls import path
from . import views
urlpatterns =[
path('list/',views.list_todo_items)
]
code of To_do/todos/view.py
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def list_todo_items(request):
return HttpResponse('from list_todo_items')
My Issue:
After using the above codes with re-directions, clearly i'm messing up somewhere, as in the "main" urls.py file present in the project directory, when I'm running my server i get the error:
$ python3 manage.py runserver
Watching for file changes with StatReloader

ModuleNotFoundError: No module named 'To_do.todos'
Clearly it is not able to find the "urls.py" file under "todos" folder, mentioned in "urls.py" in "To_do" folder.

Answer 1

As per the error path('todos/', include('To_do.todos.urls')) should be changed to: path('todos/', include('todo/',include('to_do.urls')) #to_do as the name of your app.

Answer 2

as per the error path('todos/', include('To_do.todos.urls')) should be changed to
path('todos/', include('todos.urls'))

Answer 3

Check to see if you added the todos app in the installed apps list of settings.py
INSTALLED_APPS = [
...
'todos.apps.TodosConfig'
]
stop the server ctrl + c then run server again python manage.py runserver
