Have you tried escaping the "\"?

try
 >>> os.path.exists('c:\\bookmarks.html')

'\w' is not a special sequence and therefore gets automagically 
translated to the escaped "\\w", but "\b" is equivalent to "\x08" and 
your functions therefore see the string "c;\x08ookmarks.html".

If you don't want to escape your strings, use rawstrings (prepend your 
strings with "r", "c:\bookmarks.html" therefore becomes
r"c:\bookmarks.html")
