  <p>The code of the python file is:</p>
  
  <pre><code>#! /usr/bin/python

          if t == "/test/topic":
              if n == "test": 
          print "test message received"
  
  # create broker
  mqttc = mosquitto.Mosquitto("python_sub")

  #connect
  mqttc.connect(broker, 1883, 60, True)

  mqttc.subscribe("/test/topic", 2)
  
  #keep connected
