PYTHON的Django之learning_log404問題

小白請指教，learing_log的URL文件如下：
from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
url(r’learing_logs/ ‘,include((‘learing_logs.urls’, ‘learing_logs’), namespace=‘learing_logs’)),
url(r’^admin/’, admin.site.urls),
]
爲什麼http://localhost:8000/報錯
