Problem tu use zabbix api

[angelhc]

Hello all,
I just develop a new scrip to add items to a defined host.
The script is a copy/paste from
https://github.com/gescheit/scripts/tree/master/zabbix/ and I call it add_item_api.py:
from zabbix_api import ZabbixAPI

server="127.0.0.1"
username="api"
password="apipass"

zapi = ZabbixAPI(server=server, path="/zabbix/", log_level=3)
zapi.login(username, password)

host_name="test"
description='Pruebas de api $1 en %'
key='vfs.fs.size[/,pused]'

hostid=zapi.host.get({"filter":{"host":host_name}} )[0]["hostid"]
print hostid
zapi.item.create({ 'hostid' : (hostid),'description' : (description),'key_' : key })

But when I execute it the json show this_

[root@zabpro01 api]# python add_item_api.py

The user api with apipass is created into API access group
What am I do incorrectly?
Thanks all!

Finally the problem was the json call method, the system didn't find the python simplejson.
It's solved.
Thanks all.
