I want to make a Python scr

Answer 1

Too much complications

What is the reason to split the bytes object by newline or by other array manipulations? I write the simplest method, which will solve your problem:

import serial
s = serial.Serial(31)
s.write(bytes("ATI\r\n", "utf-8"));
while True:
    last = ''
    for byte in s.read(s.inWaiting()): last += chr(byte)
    if len(last) > 0:
        # Do whatever you want with last
        print (bytes(last, "utf-8"))
        last = ''
