I'm trying to make a program that allows me whenever the user want, shutdown or restart the computer. I'll send this to my friends so I don't know which operating system. I'm using tkinter too,here is an example codes;

```
import subprocess
import os

time = "10"

if os.name == "posix":
    subprocess.call(["shutdown", "-h", time])
elif os.name == "nt":
   subprocess.call(["shutdown", "-s", "-t", time]) 

```

However, on linux, it's asking password to user before shutting down. So this program is useless if asking password before shutting down. I tried to use `%admin ALL = NOPASSWD: /sbin/shutdown` after `if` statement but it doesn't work either. How to pass this password thing on linux?
