There aren't. The error message is just showing the repr() of the
string, which involves escaping any literal backslashes in it; note
the quotes around the path in the error message.
Details on repr(): http://docs.python.org/library/functions.html#repr
By way of example:
>>> x = raw_input()
C:\foo\bar
>>> print x
C:\foo\bar
>>> print repr(x)
'C:\\foo\\bar'
>>> print('C:\\foo\\bar')
C:\foo\bar
Note that you can use forward slashes instead of backslashes in
Windows paths in Python, thus avoiding this confusion altogether.
Cheers,
Chris
