os.chmod(path,mode) 這個方法應(yīng)該很簡單，只需要2個參數(shù)，一個是路徑，一個是說明路徑的模式，下面列出了這個用法中可以使用的一些常用的模式：

stat.S_ISUID: Set user ID on execution. 不常用

stat.S_ISGID: Set group ID on execution. 不常用

stat.S_ENFMT: Record locking enforced. 不常用

stat.S_ISVTX: Save text image after execution. 在執(zhí)行之后保存文字和圖片

stat.S_IREAD: Read by owner. 對于擁有者讀的權(quán)限

stat.S_IWRITE: Write by owner. 對于擁有者寫的權(quán)限

stat.S_IEXEC: Execute by owner. 對于擁有者執(zhí)行的權(quán)限

stat.S_IRWXU: Read, write, and execute by owner. 對于擁有者讀寫執(zhí)行的權(quán)限

stat.S_IRUSR: Read by owner. 對于擁有者讀的權(quán)限

stat.S_IWUSR: Write by owner. 對于擁有者寫的權(quán)限

stat.S_IXUSR: Execute by owner. 對于擁有者執(zhí)行的權(quán)限

stat.S_IRWXG: Read, write, and execute by group. 對于同組的人讀寫執(zhí)行的權(quán)限

stat.S_IRGRP: Read by group. 對于同組讀的權(quán)限

stat.S_IWGRP: Write by group. 對于同組寫的權(quán)限

stat.S_IXGRP: Execute by group. 對于同組執(zhí)行的權(quán)限

stat.S_IRWXO: Read, write, and execute by others. 對于其他組讀寫執(zhí)行的權(quán)限

stat.S_IROTH: Read by others. 對于其他組讀的權(quán)限

stat.S_IWOTH: Write by others. 對于其他組寫的權(quán)限

stat.S_IXOTH: Execute by others. 對于其他組執(zhí)行的權(quán)限

>>> os.stat('test')

posix.stat_result(st_mode=33204, st_ino=93328670, st_dev=18L, st_nlink=1, st_uid=30448, st_gid=1000, st_size=0, st_atime=1445932321, st_mtime=1445932321, st_ctime=1445932321)

>>> os.stat('test').st_mode

33204

>>> oct(os.stat('test').st_mode)

'0100664'

>>> oct(os.stat('test').st_mode)[-3:]

'664'
