title: Django tutorial, Getting: TypeError at /admin/ argument to reversed() must be a sequence
body: <p>I'm working my way through the django tutorial for version 1.8 and I am getting an error that I am stuck on and can't seem to figure out. I thought I was following the tutorial pretty much to the T. </p>
  
  <p>I have the following tree set up:</p>
  
  <p><code>.
  ├── dj_project
  │   ├── __init__.py
  │   ├── __init__.pyc
  │   ├── settings.py
  │   ├── settings.pyc
  │   ├── urls.py
  │   ├── urls.pyc
  │   ├── wsgi.py
  │   └── wsgi.pyc
  ├── manage.py
  └── polls
      ├── admin.py
      ├── admin.pyc
      ├── __init__.py
      ├── __init__.pyc
      ├── migrations
      │   ├── 0001_initial.py
      │   ├── 0001_initial.pyc
      │   ├── __init__.py
      │   └── __init__.pyc
      ├── models.py
      ├── models.pyc
      ├── tests.py
      ├── urls.py
      ├── urls.pyc
      ├── views.py
      └── views.pyc
  </code></p>
  
  <p>and have, just as in the tutorial for <strong>polls/urls.py</strong>:</p>
  
  <pre><code>from django.conf.urls import url
  
  from . import views
  
  urlpatterns = {
      url(r'^$', views.index, name='index'),
  }
  </code></pre>
  
  <p>and for my <strong>dj_project/urls.py</strong>: </p>
  
  <pre><code>from django.conf.urls import include, url
  from django.contrib import admin
  
  urlpatterns = [
  
      url(r'^polls/', include('polls.urls')), 
      url(r'^admin/', include(admin.site.urls)),
  
  ]
  </code></pre>
  
  <p>and in <strong>polls/views.py</strong> i have:</p>
  
  <pre><code>from django.shortcuts import render
  from django.http import HttpResponse
  
  def index(request):
      return HttpResponse("is there something here?")
  </code></pre>
  
  <p>so when I go to <code>&lt;mysite&gt;/polls</code> I see "is there something here", but if I go to <code>&lt;mysite&gt;/admin</code>, I get the error: <code>TypeError at /admin/ argument to reversed() must be a sequence</code>. If I remove polls from urlpatterns in <code>dj_project/urls.py</code>, the admin comes in fine. </p>
  
  <p>What might be the problem? I can't seem to figure it out.</p>
