The easy way to execute sudo command in Python using subprocess.Popen

run a command as root using sudo from Python:

import subprocess

def mypass():
    mypass = '123' #or get the password from anywhere
    return mypass

echo = subprocess.Popen(['echo',mypass()],
                        stdout=subprocess.PIPE,
                        )

sudo = subprocess.Popen(['sudo','-S','iptables','-L'],
                        stdin=echo.stdout,
                        stdout=subprocess.PIPE,
                        )

end_of_pipe = sudo.stdout

print "Password ok \n Iptables Chains %s" % end_of_pipe.read()
