Estoy siguiendo el tutorial en el sitio de Django para crear una aplicación de encuesta simple. Sin embargo, Django no puede resolver "//127.0.0.1:8000/polls", aunque he definido la expresión regular en mySite / urls.py. Estoy haciendo esto en un virtualenv, con el último Django (1.7) instalado.

mySite / urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^polls/', include('polls.urls')),
)

mySite / polls / urls.py:

from django.conf.urls import patterns, url
from polls import views

urlpatterns = patterns('',
url(r'^
mySite / polls / views.py:
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")
mySite / settings.py:
 ...
 INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
 ) 
  ....
 ROOT_URLCONF = 'mySite.urls'
El error que estoy recibiendo:
Using the URLconf defined in mySite.urls, Django tried these URL patterns, in this order: ^admin/  
The current URL, polls, didn't match any of these.
