Python code for Configuring PubNub

from pubnub.pnconfiguration import PNConfiguration

from pubnub.pubnub import PubNub, SubscribeListener

from pubnub.enums import PNStatusCategory

pnconfig = PNConfiguration()

pnconfig.publish_key = "pub-c-097ac4e7-23cf-45ee-980f-1775137fdf4e"

pnconfig.subscribe_key = "sub-c-a3cd0700-2bcd-11e7-97de-0619f8945a4f"

pnconfig.secret_key="sec-c-NzJhOGJlZmItNzQ2OC00MmM2LTg3ZjAtNWUxOWE2MjY4NTgx"

pnconfig.uuid="test"

pubnub = PubNub(pnconfig)


Connecting to broker

my_listener = SubscribeListener()

pubnub.add_listener(my_listener)

pubnub.subscribe().channels('mytopic/new').execute()

my_listener.wait_for_connect()

print('connected')


pubnub.publish().channel('mytopic/new').message({'fieldA': 'awesome', 'fieldB': 10}).sync()
