第二個檔案:/home/virtualenvs/01-sunck/project/myApp/urls.py
from django.urls import path
from . import views
urlpatterns = [
path('',views.index),
path('<int:num>',views.detail),
path('grades/',views.grades),
path('students/',views.students),
]
第三個檔案:/home/virtualenvs/01-sunck/project/project/urls.py
from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('',include('myApp.urls')),
