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 - mode may 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.
