# Python3 program to change directory 
# of file using os.chflags() method
# import os library
import os
# defining path and flag
path = "gfg_dir/geek.txt"
flag = os..UF_IMMUTABLE
# assigning val to function chflags()
val = os.chflags(path, flag)
# Doesn't return any value, so
# nothing will be printed
print("Operation successful, returning value: %s" %val)
