If you care about what *kind* of drives you get, there are a number of drive
type constants defined:

* win32file.DRIVE_CDROM
* win32file.DRIVE_FIXED
* win32file.DRIVE_NO_ROOT_DIR
* win32file.DRIVE_RAMDISK
* win32file.DRIVE_REMOTE
* win32file.DRIVE_REMOVABLE
* win32file.DRIVE_UNKNOWN

So, for example, if you wanted just the local drives, you could do:

localdrives = [drive for drive in
win32api.GetLogicalDriveStrings().split('\x00')[:-1] if
win32file.GetDriveType(drive) in [win32file.DRIVE_FIXED,
win32file.DRIVE_CDROM, win32file.DRIVE_REMOVABLE]]
