 from django.shortcuts import render
 from django.http import HttpResponse 
# Create your views here.
 def index(request):
return HttpResponse("Hello World!")

adding url

from first_app import views

urlpatterns = [
    url(r'^$',views.index,name='index'),
    path('admin/', admin.site.urls),
]

Answer 1

您需要导入url，以便可以在urls.py中使用它

from django.urls import path
from django.conf.urls import url

from first_app import views

urlpatterns = [
    url(r'^$',views.index,name='index'),
    path('admin/', admin.site.urls),
]

您应该意识到url是定义网址格式的旧方法，将来可能会弃用

vscode anacondapython中的未定义变量URL
