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. 
os.chmod("/Geeks/gfg.txt", stat.S_IROTH) 
print("File access changed, can be read by others now.") 

Output:

File can be read only by owner.
File access changed, can be read by others now.

Code #2:

# Python program to explain os.chmod() method

os.chmod("/Geeks/gfg.txt", stat.S_IXUSR) 
print("File can be written and executed only by owner.")
