升級到Django2.0後，URL配置發生了一些變化

以最簡單的Hello World為例：

views.py

from django.http import  HttpResponse

def hello(request):
	return HttpResponse('Hello World!')

若為Django 1.8 

urls.py 

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

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

若為Django 2.0 

from django.contrib import admin
from django.urls import path
from firstapp import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('hello/',views.hello)
]
