Я не могу INSERT INTO переменной в MYSQL с Python3

Question

import MySQLdb 
# Open database connection 
payload_list = ["10","20","30","40"] 
db = MySQLdb.connect("localhost","","","iot") 

# prepare a cursor object using cursor() method 
cursor = db.cursor() 

# execute SQL query using execute() method. 
sql = "INSERT INTO iot_data (data_ip,data_mac,data_humidity,data_temp,data_time) VALUES('%s', '%s', '%s', '$s', NOW()))" 
cursor.execute("INSERT INTO iot_data (data_ip,data_mac,data_humidity,data_temp,data_time) VALUES('%s', '%s', '%s', '$s', NOW()))",(payload_list)) 

# Fetch a single row using fetchone() method. 
db.commit() 

# disconnect from server 
db.close() 

Ошибка

Traceback (most recent call last): File "db.py", line 13, in cursor.execute("INSERT INTO iot_data (data_ip,data_mac,data_humidity,data_temp,data_time) VALUES('%s', '%s', '%s', '$s', NOW()))",(payload_list[0],payload_list[1],payload_list[2],payload_list[3],)) File "/usr/lib/python3/dist-packages/MySQLdb/cursors.py", line 210, in execute query = query % args TypeError: not all arguments converted during string formatting

Вот мое решение

#!/usr/bin/python3 
import datetime 
import MySQLdb 
# Open database connection 
payload_list = ["HI",2,3,4] 
db = MySQLdb.connect("localhost","","","iot") 

# prepare a cursor object using cursor() method 
cursor = db.cursor() 
your_date = "2017-01-12 19:51:44" 
# execute SQL query using execute() method. 

sql = """INSERT INTO iot_data (data_ip,data_mac,data_humidity,data_temp,data_time) VALUES(%s, '%s', '%s', '%s', NOW())""" 
cursor.execute(sql,payload_list) 

# Fetch a single row using fetchone() method. 
db.commit() 

# disconnect from server 
db.close()
