Simple example

huawei.py

import sys
import re

from netmiko import ConnectHandler

pattern = re.compile(r'Huawei\s\w+\s\w+\suptime')
COMMAND = sys.argv[1]
USER = input('Username: ')
PASSWORD = getpass.getpass()

DEVICES_IP = ['192.168.1.2']

for IP in DEVICES_IP:
    print('Connection to device {}'.format(IP))
    DEVICES_PARAMS = {'device_type': 'huawei',
                      'ip': IP,
                      'username': USER,
                      'password': PASSWORD}
    with ConnectHandler(**DEVICES_PARAMS) as ssh:
        ssh.enable()

        result = pattern.findall(ssh.send_command('display version'))

        print(result)
