I want to get the total number of numbers on the list, so I can hear the question!

 import numpy as np

import os

import re

seoul_file = open("seoul.txt", "r", encoding = "utf8")

seoul = seoul_file.read().splitlines()

print ("Seoul Data Received"

seoul_file.close()


time12_seoul = []

date12_s = []

date12_s2 = []


def clean_text(inputString): #Remove special characters

  text_rmv = re.sub('[-=+,#/:^.@*\"※~ ·!NNone'|}\(\)\[\]`\'…》\”\“\’·]', '', str(inputString))

  return text_rmv


def list_chunk(lst,n): #Splitlist(when dividing by date)

    return [lst[i:i+n] for i in range(0, len(lst), n)]

def None_del(n,lst):

    lst.clear()

    for a in n:

        a = list(filter(None, a))
        lst.append(a)
    return lst

for s_time in seoul:     
                  #Only 12 o'clock data in Seoul is contained
    if '12:00' in s_time:

        time12_seoul.append(s_time)


for s_data12 in time12_seoul:

    list_s = s_data12.split(',')
    del list_s[0]
    del list_s[1]
    Value_seoul12 = list_s[0].split(":")
    del Value_seoul12[0]
    Value_seoul12 = clean_text(Value_seoul12)
    if Value_seoul12 == '':
        date12_s.append(Value_seoul12)
        continue
    else:
        Value_seoul12 = (Value_seoul12)
        date12_s.append(Value_seoul12)

    #print(Value_seoul12)
    Value2_seoul12 = list_s[1].split(":")
    del Value2_seoul12[0]
    Value2_seoul12 = clean_text(Value2_seoul12)

        date12_s2.append(Value2_seoul12)
    #print(Value2_seoul12)

s_12 = list_chunk(date12_s, 40)

s2_12 = list_chunk(date12_s2, 40)

date12_s = None_del(s_12, date12_s)

date12_s2 = None_del(s2_12, date12_s2)
