This is the official PubNub Python SDK repository.
Note: Python SDK version 5.0 no longer supports Python 2.7, Twisted or Tornado, if you still require support for these please use SDK version 4.8.1
PubNub takes care of the infrastructure and APIs needed for the realtime communication layer of your application. Work on your app's logic and let PubNub handle sending and receiving data across the world in less than 100ms.
You will need the publish and subscribe keys to authenticate your app. Get your keys from the Admin Portal.
-
Integrate the Python SDK into your project using
pip:pip install pubnub
-
Configure your keys:
pnconfig = PNConfiguration() pnconfig.subscribe_key = 'mySubscribeKey' pnconfig.publish_key = 'myPublishKey' pnconfig.uuid = 'myUniqueUUID' pubnub = PubNub(pnconfig)
class SubscribeHandler(SubscribeCallback):
def status(self, pubnub, event):
print("Is there an error? ", event.is_error())
print("Status value for category: %s" % event.category)
print("Status value for error_data: %s" % event.error_data)
print("Status value for error: %s" % event.error)
print("Status value for status_code: %s" % event.status_code)
print("Status value for operation: %s" % event.operation)
print("Status value for tls_enabled: %s" % event.tls_enabled)
print("Status value for uuid: %s" % event.uuid)
print("Status value for auth_key: %s" % event.auth_key)
print("Status value for origin: %s" % event.origin)
print("Status value for client_request: %s" % event.client_request)
print("Status value for client_response: %s" % event.client_response)
print("Status value for original_response: %s" % event.original_response)
print("Status value for affected_channels: %s" % event.affected_channels)
print("Status value for affected_groups: %s" % event.affected_groups)
def presence(self, pubnub, presence):
pass # Handle incoming presence data
def message(self, pubnub, message):
pass # Handle incoming messages
def signal(self, pubnub, signal):
pass # Handle incoming signals
pubnub.add_listener(SubscribeHandler())def my_publish_callback(envelope, status):
if status.is_error():
... #handle error here
else:
... #handle result here
pubnub.publish().channel('my_channel').message('Hello world!').pn_async(my_publish_callback)
pubnub.subscribe().channels('my_channel').execute()- Build your first realtime Python app with PubNub
