最新版Django用视图使用问题

　　旧版本：

　　

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^', include('booktest.urls')),
]

新版本：

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

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