Back Slash not allowed at the end of raw string?

[yuhao]

Title: Mail

I'm using Python 2.5 on Windows XP Pro. While testing for strings, I got the following result:   >>> r'c:\' SyntaxError: EOL while scanning single-quoted string >>> r'c:\nwin' 'c:\\nwin' >>> r"c:\" SyntaxError: EOL while scanning single-quoted string >>> r'\n' '\\n' >>> r'\"' '\\"' It seemed that when a back slash is inside the raw string, it is correctly recognized as a normal character, not translated; but when put to the end, it raise an error.   And the message looks so strange:   >>> r"c:\" SyntaxError: EOL while scanning single-quoted string   what does this message mean? I'm not using any single quote in the statement. It this a bug or by design?
