Change user password from python script running as user – CentOS

I’m currently working on a Python Script on a CentOs 8 VM, I’m trying to write part of my python script that will set a users password for them without user interaction. I’ve not found a way to do this yet and tried various methods like:

subprocess.run(str('echo -e "passwordnpasswordnpasswordn" | sudo -S passwd --stdin user'), shell=True, universal_newlines=True, check=True)

But to no avail.

I know this is insecure (even if it worked) but in this case, that really doesn’t matter, so, security aside I just need to make it work. The passwords are just examples to show the code as I know they would be rejected if used as the actual passwords.

Is there a way to make the script run as the root user maybe, instead of the logged-in user?

Doing a similar thing as root user works like this:

subprocess.run(str('echo -e "passwordnpassword" | passwd --stdin ' + userName), shell=True, universal_newlines=True, check=True)

it’s only when I add the sudo part I can’t auto put in the sudo password

If I do this straight from the terminal it works:

echo -e "passwordnpasswordnpassowrd" | sudo -S passwd --stdin dave

    Try using subprocess.Popen(command, 0, None, None, shell=True) like below:

    def launchCommand(command):
    proc = subprocess.Popen(command,0,None,None, shell=True)
    proc.poll()
    proc.wait()
    ret = proc.returncode
    return ret

command = str('echo -e "passwordnpasswordnpasswordn" | sudo -S passwd --stdin user')
print(launchCommand(command))
