first try with python class, suggestion for improvement please

[buran]

your def get_fan_details() method does not use the other two methods def get_fan_speed() and get_fan_status():

return {
                   'NumOfFantrays':NumFanTrays,
                   'NumofFans':NumFans,
                   'FanSpeed':self.get_fan_speed(FanSpeed),
                   'FanStatus':self.get_fan_status(FanOperStatus)
                  }

if you are not able to debug soemthing like this, better read again some class basics tutorial
