Update Mikrotik to last version

[abrpr]

how can i update my mikrotik to last version with this API?
it should first download new update with this command
system/package/update download
and then reboot the router

I did it like that :

import routeros_api
import datetime
from scanNmapy import ScanNmapy


ip_list =[]

no_access = []
comunication_error = []

update_time = datetime.datetime(2017, 9, 15, 14, 20)
delta = datetime.timedelta(days=0.0005)

length = len(ip_list)

while length != 1:
    length = len(ip_list)
    ip = ip_list.pop(0)

    time = str(update_time)[11:19]

    connection = routeros_api.RouterOsApiPool(ip, username=login, password=password)
    try:
        api = connection.get_api()
        try:
            task = api.get_resource('/system/scheduler')
            task.add(name='', start_time=time, on_event='system package update check-for-updates' + '\n' + 'system package update download')
            task.add(name='reset', start_time='03:00:00', start_date='Sep/18/2017', on_event='system reboot')
        except routeros_api.exceptions.RouterOsApiCommunicationError:
            comunication_error.append(ip)

        connection.disconnect()
        print(ip + '  Done')
    except routeros_api.exceptions.RouterOsApiConnectionError:
        print(ip + '  NOT done')
        no_access.append(ip)

    update_time = update_time + delta


print('No access :')

print(no_access)
