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.
