Syntax Error in python code for read sensor data through url and store into drive in .csv format

Question

I was writing a python script to collect data remotely from plc through URL and store those data into my drive in CSV format. I have used the urllib3 module to collect data from the remote device. The problem is whenever I am trying to decode those raw data which is coming from the remote device through URL using this code int(b.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16) the compiler shows a syntax error, but I didn't find anything wrong in this code. I am new to Python as well as Raspberry Pi, please help me to sort out the error.

My full code is

import os
import time
from time import sleep
import datetime
import urllib3


def readVoltage():
    http = urllib3.PoolManager()
    responce = http.request('GET', 'http://northam.ddns.net:9080?HOSTLINK/RVIY*')
    responce1 = http.request('GET', 'http://northam.ddns.net:9080/HOSTLINK/RVIA*')
    responce2 = http.request('GET', 'http://northam.ddns.net:9080/HOSTLINK/RVIB*')
    a, b, c = responce.data, responce1.data, responce2.data
    m = int(a.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)
    n = int(b.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)
    o = int(c.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)
    return m, n, o

def write(volt1, volt2, volt3):
    file.write(datetime.now().strftime("%Y-%m-%d %H:%M:%S")+","+str(volt1)+","+str(volt2)+","+str(volt3)+"\n")
    return


file = open("/home/oztron/Documents/datalog.csv", "a")
if os.stat("/home/oztron/Documents/datalog.csv").st_size == 0:
    file.write("Time, volt1, volt2, volt3\n")
while True:
    p, q, r = readVoltage()
    write(p, q, r)
    file.flush()
    time.sleep(2)

The error is

File "test.py", line 15
n = int(b.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)

SyntaxError: invalid syntax

Answer 1

Your problem is you have mismatched parentheses.

To fix it change these three lines:

m = int(a.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)
n = int(b.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)
o = int(c.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16)

to:

m = int(a.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16))
n = int(b.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16))
o = int(c.decode(("utf-8").spilt('RVI')[1].spilt('*')[0], 16))

Answer 2

Check your spelling: 'spilt' is not a Python object method. You want 'split'.
