In my server:

Page not found (404)

Request Method:	GET
Request URL:	http://127.0.0.1:8000/

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:

1. polls/
2. admin/

The empty path didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
