python chmod_Python os.chmod用法及代码示例

Python中的os.chmod()方法用于将路径模式更改为数字模式。

用法:

os.chmod(path, mode)

参数:

path – path name of the file or directory path

mode – modemay take one of the following values:

stat.S_ISUID : Set user ID on execution

stat.S_ISGID : Set group ID on execution

stat.S_ENFMT : Record locking enforced

stat.S_ISVTX : Save text image after execution

stat.S_IREAD : Read by owner.

stat.S_IWRITE : Write by owner.

stat.S_IEXEC : Execute by owner.

stat.S_IRWXU : Read, write, and execute by owner

stat.S_IRUSR : Read by owner

stat.S_IWUSR : Write by owner.

stat.S_IXUSR : Execute by owner.

stat.S_IRWXG : Read, write, and execute by group

stat.S_IRGRP : Read by group

stat.S_IWGRP : Write by group

stat.S_IXGRP :Execute by group

stat.S_IRWXO : Read, write, and execute by others.

stat.S_IROTH : Read by others

stat.S_IWOTH :Write by others

stat.S_IXOTH : Execute by others

代码1：

# Python program to explain os.chmod() method

# importing necessary libraries

import os, sys, stat

# Set given file read by the owner.

os.chmod(“/Geeks/gfg.txt”, stat.S_IREAD)

print(“File can be read only by owner.”)

# Set given file read by others.

os.chmod(“/Geeks/gfg.txt”, stat.S_IROTH)

print(“File access changed, can be read by others now.”)

输出：

File can be read only by owner.

File access changed, can be read by others now.

代码2：

# Python program to explain os.chmod() method

# importing necessary libraries

import os, sys, stat

# Set given file written by the owner.

os.chmod(“/Geeks/gfg.txt”, stat.S_IWRITE)

# Set given file executed by the owner.

os.chmod(“/Geeks/gfg.txt”, stat.S_IXUSR)

print(“File can be written and executed only by owner.”)

输出：

File can be written and executed only by owner.
