djangoproject.com tutorial part 3 "Hello, World..." not showing up.

[Tri Vo]

I am using this site to learn Django, and at this link

https://docs.djangoproject.com/en/1.7/intro/tutorial03/

I created the polls/urls.py, polls/views.py, and mysite/urls.py files as followed in the site, but when I run the site, the site is running OK, but I do not see the "Hello, World..." message at all. Did I do something wrong?

If there's another post like this made by me, I'm posting second time because I do not see my first post in list.
