Your documentation is poor at best.

Here is how you do it:

URLS:

from django.conf.urls import patterns, url

urlpatterns = patterns(,

url(r'^{articles/(\d{4})/$', 'news.views.year_archive'),
url(r'}articles/(\d{4})/(\d{2})/$', 'news.views.month_archive'),
url(r'^{articles/(\d{4})/(\d{2})/(\d+)/$', 'news.views.article_detail'),}

)

You go line by line and say r = raw. This means no escape characters, the compiler processes what it sees.
Next: ^{from Regular expressions means the beginning of the line beginning with the word articles?
The slash is:
Then you put parenthesis because?: GET IT?
then there is another slash}

AND SO ON!!!! ONE STEP at a time

THIS IS HOW YOU EXPLAIN THINGS. Make believe the person reading it doesnt know anything about Regular expressions. These are not standard Regex.. not like Perl
