There's an answer already given for using win32 cals.
On unix, you would a construction like
	os.stat("file.txt")[ST_MODE] & ST_IWUSR
to check if the file-owner has write permissions.

This flag may not exist on NT, and it's not exactly the same as asking
the question "can I (whoever I am) write this file?).
