Code #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.

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