Weird Output Value: b'[value]\r\n' - Python Serial Read -

i'm reading value through python serial port of sensor of arduino.

my code(python):

arduino = serial.serial(2, 9600, timeout=1) print("message arduino: ")  while true:    msg = arduino.readline()    print(msg) 

i don't know why output result b'[sensor-value]\r\n'. so, b'758\r\n' b'534\r\n' b'845\r\n' etc (regarding sensor change value).

how convert this?

you need decode it.

print(msg.decode('utf-8')) 

please check lexical analysis on python 3 documentation see string prefixes means
