Raw string fu

[Jaime Wyant]

This URL has a good section on raw strings.

http://www.ferg.org/projects/python_gotchas.html

r'\' is wrong because raw strings were originally added to make
regular expressions easier to write.  And you can't have a regexp that
ends with \.

Also, you can use the \ to escape your original quote character.

>>> r'I can\'t end strings with a \''
"I can\\'t end strings with a \\'"
