WaitSetRequest

[vladus06]

I'm trying to listen for new emails being added, getting emptiness. How can I view new letters correctly?

info_request = comm.gen_request(token=usr_token)
iinfo_request = comm.gen_request(token=usr_token)


#Create waitset
info_request.add_request(
    'CreateWaitSetRequest',
    {
	'defTypes': 'f,m,c',
	'add': {
		'a': {
		    'name': 'my@mail',
		    'types': 'f,m,c'
		},
	},
	
    },
    'urn:zimbraMail'
)
info_response = comm.send_request(info_request)
if not info_response.is_fault():
    waitset = (info_response.get_response()['CreateWaitSetResponse']['waitSet'])
    seq = (info_response.get_response()['CreateWaitSetResponse']['seq'])
    defTypes = (info_response.get_response()['CreateWaitSetResponse']['defTypes'])
......

everything above works. I get values
{u'CreateWaitSetResponse': {u'waitSet': u'WaitSet-064715ab-1867-4254-ac38-63bfd6255484', u'defTypes': u'f,m,c', u'seq': 0}}

.......
iinfo_request.add_request(
    'WaitSetRequest',
    {
	'waitSet': waitset,
	'seq': seq,
	'block': '1',
	'defTypes': defTypes,
	'timeout': '1000',
	'expand': '1',
	'add': {
		'a': {
		    'name': 'my@mail',
		    'token': '',
		    'types': defTypes
		},
	},
	
    },
    'urn:zimbraMail'
)
iinfo_response = comm.send_request(iinfo_request)
if not iinfo_response.is_fault():
    print (iinfo_response.get_response()['WaitSetResponse'])

I think the problem is here

if not iinfo_response.is_fault():
    print (iinfo_response.get_response()['WaitSetResponse'])

Result:
[root@mail zmadmin]# python ./test.py
[root@mail zmadmin]#

I want to see:
[root@mail zmadmin]# python ./test.py
{u'WaitSetResponse': {u'waitSet': u'WaitSet-064715ab-1867-4254-ac38-63bfd6255484', ... bla-bla-bla
{u'WaitSetResponse': {u'waitSet': u'WaitSet-064715ab-1867-4254-ac38-63bfd6255484', ... bla-bla-bla
{u'WaitSetResponse': {u'waitSet': u'WaitSet-064715ab-1867-4254-ac38-63bfd6255484', ... bla-bla-bla

I added values to CreateWaitSetRequest and WaitSetRequest
'token': '401',

Result:
[root@mail zmadmin]# python ./test.py
{u'a': {u'id': u'7ac0ebb7-2bd5-4c48-828c-74cbc0e636d1', u'changeid': 4136}, u'waitSet': u'WaitSet-aadbba9d-1385-4f2b-97a6-a508776ed050', u'seq': u'2', u'error': {u'type': u'ALREADY_IN_SET_DURING_ADD', u'id': u'7ac0ebb7-2bd5-4c48-828c-74cbc0e636d1'}}

How to listen to messages continuously?
