when I call the script I get an error:
mqtt_Publish_Dummy_Data.py", line 27
print "Unable to connect to MQTT Broker..."
^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Unable to connect to MQTT Broker...")?

I am working in Windows

After I initialize DB, and publish fake data. when I start listening on these data, it gives me such an error(check the attached image), what's the problem then?

mqtt_Publish_Dummy_Data.py is working fine, but with mqtt_Listen_Sensor_Data.py I have an issue with on_connect command:

python mqtt_Listen_Sensor_Data.py Traceback (most recent call last): File "mqtt_Listen_Sensor_Data.py", line 45, in <module> mqttc.loop_forever() File "/usr/lib/python2.7/site-packages/paho/mqtt/client.py", line 1481, in loop_forever rc = self.loop(timeout, max_packets) File "/usr/lib/python2.7/site-packages/paho/mqtt/client.py", line 1003, in loop rc = self.loop_read(max_packets) File "/usr/lib/python2.7/site-packages/paho/mqtt/client.py", line 1284, in loop_read rc = self._packet_read() File "/usr/lib/python2.7/site-packages/paho/mqtt/client.py", line 1849, in _packet_read rc = self._packet_handle() File "/usr/lib/python2.7/site-packages/paho/mqtt/client.py", line 2311, in _packet_handle return self._handle_connack() File "/usr/lib/python2.7/site-packages/paho/mqtt/client.py", line 2372, in _handle_connack self.on_connect(self, self._userdata, flags_dict, result) TypeError: on_connect() takes exactly 3 arguments (4 given)

Line print "Data: " + msg.payload on the file mqtt_Listen_Sensor_Data.py can't print the content of the payload. The value cames as byte. I already used the decode('utf-8') to fix it.

print ("Data: " + msg.payload.decode('utf-8'))

I'm using Python3.
