12. URL Dispatcher
 Root URL should be configured in settings.py
o ROOT_URLCONF = 'app.urls'
 Syntax
– patterns(prefix,
(regular expression, Python callback function [, optional dictionary [, optional name]]) )
– Example:
– urlpatterns = patterns(' ', (r'^articles-year/$', 'mysite.news.views.articles_year'))
– Note:
o No need to add a leading slash (/articles-year)
o The 'r' in front of each regular expression string is optional but recommended. It
tells Python that a string is "raw" -- that nothing in the string should be escaped.
