A simple container object for the two components of a message in the arg1 messaging protocol: the topic and the user data. Each listener called by sendMessage(topic, data) gets an instance of Message. The given ‘data’ is accessed via Message.data, while the topic name is available in Message.topic:
def listener(msg):
print("data is %s" % msg.data)
print("topic name is %s" % msg.topic)
print(msg)
The example also shows (last line) how a message is convertible to a string.
