Python Django错误{未找到页面，错误404}，

[目录]尝试连接时出现此错误

Using the URLconf defined in project.urls, Django tried 
these URL patterns, in this order:

admin/
 The current path, polls/, didn't match any of these.

C:\Users\Kwaku-Biney\Desktop\dj\mysite\polls\url.py

 from django.urls import path
  from . import views
urlpatterns = [
path('', views.index, name='index'),]

C:\Users\Kwaku-Biney\Desktop\dj\mysite\mysite\url.py

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

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

mysite\polls\views.py

 from django.shortcuts import render
 from django.http import HttpResponse
 def index(request):
return HttpResponse("Hello, world. You're at the polls index.")

运行服务器后，问题是我没有保存文件。通过在windows上的VSCode中按CTRL+K+S来实现

您也可以通过菜单栏上的File=>AutoSave来打开VsCode上的AutoSave。

在设置中，ROOT\u URLCONF中的内容是什么？ROOT\u URLCONF='mysite.urls'您可以添加polls/apps.py吗？@BriseBalloches添加了它now@KwakuE.Biney您是否可以添加错误的屏幕截图而不是错误本身
