Use of regex in this video? Where is re being imported? and why r'^$' rather than r'' ?
I am not seeing where the re module is being imported in either views.py or urls.py- does it not need to explicitly be imported?
Also, Kenneth uses
url(r'^$', views.hello_world) in the urls.py file. Would
url(r'', views.hello_world) not be correct? I tried both with the same results.

I believe r'' is a python statement, not a Django-specific module. That's why you don't need to import it. Also, r'' is the same as r'^$' because the base url of your site does not have anything that comes after it. I hope this answer your question.
