Django email addresses

I would like to use the admin website directly with a reverse url in my Django app, but I am getting this error: No module named admin.site.urls

I have a urls.py file that looks like this:

import os
from django.conf.urls import url, include
from django.contrib import admin
from django.conf.urls.static import static
from django.conf import settings

from BirthCertificate import views
from Identity import views
from Accueil import views
from log import views
from Mairie import views
from Table import views
from Recensement import views
from Configurations import views
from Mariage import views

import debug_toolbar

from django.views.generic.base import TemplateView


urlpatterns = [
    url(r'^$', TemplateView.as_view(template_name=os.path.join(settings.BASE_DIR, 'Accueil/templates/Choice.html')),
        name='choice'),
    url(r'^admin/', include('admin.site.urls')),
    url(r'^BirthCertificate/', include('BirthCertificate.urls')),
    url(r'^Identity/', include('Identity.urls')),
    url(r'^Accueil/', include('Accueil.urls')),
    url(r'^Home/', include('log.urls')),
    url(r'^Mairie/', include('Mairie.urls')), 
    url(r'^Table/', include('Table.urls')), 
    url(r'^Recensement/', include('Recensement.urls')),
    url(r'^Configurations/', include('Configurations.urls')),
    url(r'^__debug__/', include(debug_toolbar.urls)),
    url(r'^Mariage/', include('Mariage.urls')),
] 

      

        
        
        
      

    

And one of my HTML templates:

{% if request.user|has_group:"admin" %}
    <li><a href="{% url "admin" %}" ><span class="glyphicon glyphicon-log-out"></span> Administration </a></li>
{% endif %}

      

        
        
        
      

    

Something is wrong? I can't find how I can resolve this error.
