i executing sudo statement python on uwsgi. configured account (www-data) not need password sudo not work.

if run shell, works desired account:

www-data@srv sudo iptables -l -n 

but script , uwsgi, prompts password.

in sudoers have:

www-data all=(all) nopasswd: /sbin/iptables 

and in python script:

subprocess.call(['sudo', '/sbin/iptables -l -n'])
