-Examples:
-Function views
-    1. Add an import:  from my_app import views
-    2. Add a URL to urlpatterns:  path('', views.home, name='home')
-Class-based views
-    1. Add an import:  from other_app.views import Home
-    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
-Including another URLconf
-    1. Import the include() function: from django.urls import include, path
-    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
