Django сервер не работает после добавления новой функции пути

Question

Я создал приложение с именем «cal c» в Django и в приложении отредактировал два кода файлов.
urls.py

from django.urls import path


from . import views

urlpattern = [
    path('', views.home, name='home')
]

views.py

from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.

def home(request):
    return HttpResponse("Hello Django!") 

и, наконец, я изменил файл папки моего каталога urls.py

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

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

теперь я Я запускаю команду на терминале: python manage.py runserver
, и он дает мне следующие ошибки и не подключается к серверу.

ошибки терминала:

* Watching for file changes with StatReloader
Performing system checks...

Exception in thread django-main-thread:

During handling of the above exception, another exception occurred:

Answer 1

Я вижу простую опечатку .. в вашем urls.py должно быть urlpatterns=[] вместо urlpattern=[]

Answer 2

Вы создали два пути в urls.py для страницы /. Насколько я знаю, это неправильный путь. вы можете сделать это в своем URL

path('', include('calc.urls')),

path('home/', views.home, name='home')

, а затем загрузить его localhost: 8000 / home /, и он будет работать
