from django.conf.urls import include, url django.contrib import admin  urlpatterns = [     url(r'^admin/', include(admin.site.urls)),     url(r'^polls/', include('polls.urls', namespace='polls')), ] 

you haven't got view named "polls:result", have 1 named "polls:results". either change name in polls/urls.py, or value use in call reverse in vote view.
