TypeError: 'list' object is not callable

Question

python manage.py test polls　とコマンドを打つと、TypeError: 'list' object is not callableというエラーが出ました。
https://docs.djangoproject.com/ja/2.0/intro/tutorial04/
をみながら勉強しています。

urls.pyに

from sys import path

from . import views

app_name = 'polls'

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

と書きました。
from django.urls import path　がなぜかインポートできなかったので、IDE上からインポートできたfrom sys import pathを使いました。

TypeError: 'list' object is not callable

と出ました。
チュートリアルを丸コピして試したので、なぜこのエラーが出るのかわかりません。
どう直せば良いでしょうか？

Answer 1

from django.urls import pathとfrom sys import pathは同じものではないということです。

https://docs.djangoproject.com/en/2.0/ref/urls/#path
path()にNew in Django 2.0.とあるのでDjangoが正しいバージョンであるのかを確認すべきかもしれません。

Answer 2

>>> import sys
>>> type(sys.path)
<class 'list'>
>>> []()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'list' object is not callable

from django.urls import path　がなぜかインポートできなかったので、IDE上からインポートできたfrom sys import pathを使いました。

原因は明らかですね。
