There is a more elegant solution: use raw strings: r'c:\foo\bar'

The "correct" solution in many cases is to not assume any particular
path separator at all, and use os.path.join when dealing with paths.
This will work even on systems that do not accept forward slashes as
path separators. (does Python still support any of those?)

This, of course, is the only truly tenable solution.
