How to change the owner and permissions of a file using python?

Question

linux

Good afternoon, I'm trying to change the rights and user on a file in Linux with the following script:

#!/usr/bin/python3
import os, grp, pwd
uid = pwd.getpwnam("myuser").pw_uid
gid = grp.getgrnam("myuser").gr_gid
os.chmod("/tmpjcef-p11500_scheme.tmp", 0o777)
os.chown("/tmpjcef-p11500_scheme.tmp", uid,gid)

in response I receive

Traceback (most recent call last):
  File "/home/myuser/PycharmProjects/proj5/main.py", line 15, in <module>
    os.chmod("/tmpjcef-p11500_scheme.tmp", 0o777)
PermissionError: [Errno 1] Operation not permitted: '/tmpjcef-p11500_scheme.tmp'

Answer 1

777 changes permissions for root too, so you need to run the script from under sudo to change it. Or you can look at other flags instead of 777 that do not require root rights

Answer 2

Operation not permitted

It says that you do not have rights to execute the command
, so run the script as root
