Python Error: name 'admin' is not defined

Question

I am creating a Python application in Django for the first time. I know that I must uncomment the admin tools in the urls.py, I have done that. I have also added autodiscover. Everytime I try to add a new feature to the administration panel, I get this error:

"NameError: name 'admin' is not defined"

Here is the code I am using in my model to add to the admin panel:

class ChoiceInline(admin.StackedInline):
    model = Choice
    extra = 3

    class PollAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [ChoiceInline]

here is the code in the python terminal I am using

admin.site.register(Poll, PollAdmin)

and here is the code from my urls.py:

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

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'iFriends.views.home', name='home'),
    # url(r'^iFriends/', include('iFriends.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
    )

Anyone have any idea why it cannot find the admin name?

EDIT

Here is my entire model file:

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    def __unicode__(self):
        return self.question
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

    class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField()
    def __unicode__(self):
        return self.choice_text


#COMMENTED OUT UNTIL I FIX THE ADMIN NAME
from django.config import admin

class ChoiceInline(admin.StackedInline):
    model = Choice
    extra = 3

    class PollAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [ChoiceInline]

#ADD THIS TO THE MAIN PYTHON FUNCTION
admin.site.register(Poll, PollAdmin)

Answer 1

from django.config import admin should be from django.contrib import admin
