# The hostname at which the Zabbix web interface is available
ZABBIX_SERVER = 'http://localhost/'

zapi = ZabbixAPI(ZABBIX_SERVER)

# Login to the Zabbix API
zapi.login('Admin', 'zabbix')


#zapi.do_request('host.get', { 'filter': {'host': sys.argv[1]}, 'output': 'hostid'})

print res2[3]
To update visiable name I need additional line:
zabbix_hostid = res2[3]
zapi.do_request('host.update', {'hostid': zabbix_hostid,'name': 'Visiable name'})
