Save configuration with Netmiko

from netmiko import ConnectHandler

import time

import datetime

IP_List = open('IPs.txt')

for IP in IP_List:

    SWS = {

    'device_type': 'huawei',

    'ip': IP,

    'username': 'user',

    'password': 'Password',

    }

 print ('\n ##### connection to device' + IP.strip() + '##### \n')

    net_connect = ConnectHandler(**SWS)

    config_commands = [ 'aaa',

                        'local-user user1 password cipher 0000000',

                        'local-user user1 privilege level 3',

                        'local-user user1 service-type ssh',

                        'quit',

                        'stelnet server enable',

                        'ssh user user1 authentication-type password',

                        'ssh user user1 service-type stelnet',

                        'user-interface vty 0 4',

                        'authentication-mode aaa',

                        'protocol inbound ssh']

I put it in three parts because dont accept here in one part

the script works ok , but when add (return) or (save ) commands it gives error
