SyntaxError：polls//urls.py 中的語法無效。 為什么我會收到此錯誤？

Question

我正在使用 django 3.1.7 並按照它創建應用程序文檔。 我被困在第 3 部分，因為它給出了語法錯誤。

這是 urls.py：

from django.urls import path
from polls import views

urlpatterns = [
    path('',views.index, name='index'),
    path('<int:question_id>/', views.detail, name='detail'),
    path('<int:question_id>/results/', views.results, name='results'),
    path('<int:question_id>/vote/', views.vote, name='vote'),
]

錯誤：

“C:\Users\ORCUN\OneDrive\Masaüstü\WebDeveloperBootcamp\DjangoProject\rookieCoder\polls\urls.py”，第 7 行路徑（'int:question_id/results/'），views.results，name='results'），

我對名字缺少什么？ 我該如何解決？

Answer 1

錯誤在這里：

path('<int:question_id>/results/'), views.results, name='results'),

額外的右括號在傳遞其他 arguments 之前結束路徑方法調用。 將其更改為：

path('<int:question_id>/results/', views.results, name='results'),
