Raspberry Pi Serial Communication

Serial.py

'''
This program is designed to be used on the Raspberry
Pi only or any other device which accepts Python and
can do serial communication.

You will not find the module serial in your Python
which has been downloaded. You need to download it
seperately.

This code originally came from the repository Zumo
Robots, link below - 

https://github.com/rudrathegreat/Zumo-Robots

And this program is decoding whatever the Arduino
is trying to tell it (in that case, hello!)
'''

import serial
from time import sleep

PORT = '/dev/ttyUSB0' # Or /dev/ttyACM0
BAUD = 9600

s = serial.Serial(PORT)
s.baudrate = BAUD

s.parity = serial.PARITY_NONE
s.databits = serial.EIGHTBITS
s.stopbits = serial.STOPBITS_ONE

while True:

    data = s.readline().decode('UTF-8')
    data_list = data.rstrip().split(' ')
    print(data_list[0])
    sleep(1)
