How to check the read/write status of storage media in python?

How can i check the read/ write permission of the file storing media? ie assume i have to write some file inside a directory and that directory may be available on read only media like (cd or dvd)or etc. So how can i check that storing media ( cd, hard disk) having a read only or read write both permission.

I am using windows xp os.

Thanks.

import os
from stat import *

if S_IMODE(os.stat(dir_name)) & S_IWRITE != 0:

is more portable, if not necessarily more readable.

Use the os.access(path, mode) function. It should be much more portable than the win32api function. Though, I have no experience with it on non-POSIX systems.

On the other hand, why don't you just try to write the file and handle exception appropriately?

Use the win32api.GetFileAttributes method.
