Yes http://docs.python.org/reference/lexical_analysis.html#string-literals Specifically, a raw string cannot end in a single backslash (since the backslash would escape the following quote character). The usual way round this is like this >>> r"a" "\\" 'a\\' >>> Which isn't terribly elegant, but it doesn't happen very often. -- Nick Craig-Wood <n...@craig-wood.com> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list
