How to insert rows of information into different rows in a mysql database?

I don't know how to insert a list of info into a mysql database.

I'm trying to insert rows data into a database but it is simply inserting the last row three times. The list is named "t" and it is a tuple .

Data:

11/04/19,17:33,33.4,55
11/04/19,17:34,22.9,57
11/04/19,17:35,11.9,81

Code:

import mysql.connector

sql = mysql.connector.connect(
    host='    ',
    user='    ',
    password='    ',
    db="     "
    )
cursor = sql.cursor()

f = open("C:\Cumulus\data\Apr19log.txt","r")

while True:
    s = f.readline()
    list=[]
    if (s != ""):
        t=s.split(',')
        for item in t:
            list.append(item)
    else:
        break;


sqllist =    """INSERT INTO station_fenelon (variable, date,             
time,outside_temp, outside_humidity)  
                VALUES (%s, %s, %s, %s, %s)"""

record =[(1, t[0], t[1], t[2],t[3]),
         (2, t[0], t[1], t[2],t[3]),
         (3, t[0], t[1], t[2],t[3])]

cursor.executemany(sqllist, record)
sql.commit()

I want to create three rows in the database with this list of information but is is only showing the last row of information in the database.

Try this.

import mysql.connector
sql = mysql.connector.connect(host='',user='',password='',db='')
cursor = sql.cursor()
f = open("C:\Cumulus\data\Apr19log.txt","r")
st=[i.strip().split(',') for i in f.readlines()]

sqllist = """INSERT INTO station_fenelon (variable, date, time, outside_temp, outside_humidity) VALUES (%s, %s, %s, %s, %s)"""

record = [(i+1, j[0], j[1], j[2], j[3]) for i, j in enumerate(st)]

cursor.executemany(sqllist, record)
sql.commit()
