r"testing " backslash and quote" 'testing \" backslash and quote' It happens that this is the behavior I want, but it seemed just as likely to be an error. I tested it with python2.5 and 2.6 and got the same results.
The behaviour does appear to be explicitly documented in the language reference:
""" When an 'r' or 'R' prefix is present, a character following a backslash is included in the string without change, and all backslashes are left in the string. For example, the string literal r"\n" consists of two characters: a backslash and a lowercase 'n'. String quotes can be escaped with a backslash, but the backslash remains in the string; for example, r""" is a valid string literal consisting of two characters: a backslash and a double quote; r"" is not a valid string literal (even a raw string cannot end in an odd number of backslashes).
