r before a python String

One more important detail we’ve introduced here is that r character in front of the regular expression string. This tells Python that the string is a “raw string” – its contents should not interpret backslashes. In normal Python strings, backslashes are used for escaping special characters – such as in the string '\n', which is a one-character string containing a newline. When you add the r to make it a raw string, Python does not apply its backslash escaping – so, r'\n' is a two-character string containing a literal backslash and a lowercase “n”. There’s a natural collision between Python’s usage of backslashes and the backslashes that are found in regular expressions, so it’s strongly suggested that you use raw strings any time you’re defining a regular expression in Python. From now on, all of the URLpatterns in this book will be raw strings.

Django Slashes

If you’re the type of person who likes all URLs to end with slashes (which is the preference of Django’s developers), all you’ll need to do is add a trailing slash to each URLpattern and leave APPEND_SLASH set to True. If you prefer your URLs not to have trailing slashes, or if you want to decide it on a per-URL basis, set APPEND_SLASH to False and put trailing slashes in your URLpatterns as you see fit.
