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.
