python-3.6 - 找不到django页面帮助我

Question

这是我项目中的 URL

from django.contrib import admin
from django.urls import path,include
urlpatterns = [
    path('admin/', admin.site.urls),
    path(r"^app/",include(("app.urls","app"),namespace="app")),
    path(r"^/",include("web.urls")),
]

这是我的网络应用程序中的 URL

from django.conf.urls import  url,include
from  web.views  import  account

urlpatterns = [
    url(r"^register/$",account.register,name="register")
]

为什么访问 http://127.0.0.1:8000/register/ 页面找不到 404 ????? 帮我
