From the doc: http://docs.python.org/2/reference/lexical_analysis.html r"\" is not a valid string literal (even a raw string cannot end in an odd number of backslashes). Specifically, a raw string cannot end in a single backslash (since the backslash would escape the following quote character).
If it's a raw string, then the backslash will not escape the following quote character. Ergo r"\" should be allowed. Regards, Scot Kelly "Be excellent to each other."
