how can read message, how can I decode my recieved message?

Hi there,

I am try to learning a home automation system on Raspberry pi through GSM, but unfortunetally I am getting error in my python coding.
The Problem is When I want to print my received message that time I am getting this kind of response b'b\xf1\xe2\xe2\xe2' ,
So, I cant able to decode that message and If I decode that the python giving me a error like unorderable types: int() < str(().

So , I am really confused about it , can anybody help me out in this problem, How I can match my actual message and print?

here is my code and its output.

import serial
import time
import os

print('Welcome to Test GSM SIM900')
ser = serial.Serial ("/dev/ttyS0", 19200, timeout=1) #9600 is the default for SIM900A modem
print('Waiting for Response')

ser.write(('AT+CMGF=1' + '\r').encode('utf-8'))
time.sleep(1)
print('Connection Establish')
ser.write(('AT+CMGDA="DEL ALL"'+'\r').encode('utf-8'))
time.sleep(1)
print('All messages has been Deleted')

message = ser.read(1000) # inWaiting- get the number of bytes in the inout buffer

print(message)

while True:
      if message == 'LED1':
          print ("LED 1 is on")
      elif message == 'LED2':
          print ("LED 2 is on")
      elif message == 'EXIT':
          print ("shuting down")
          ser.close ()
          break
      else:
          print ("Try again")
          break

ser.close() #close the serial port
