Mysql python3中Insert data中的SQL语句中没有使用所有参数

我使用Python3，想从网站上抓取数据。我创建了一个数据库，你可以监视我的代码。 我可以轻松、清晰地从网上搜集数据。但是我不能在数据库中插入数据

import requests
from bs4 import BeautifulSoup
import mysql.connector
from mysql.connector import errorcode


def req(carname):
    try:
        URL = 'https://www.truecar.com/used-cars-for-sale/listings/' + carname + '/?sort[]=best_match'
        req = requests.get(URL)
        soup = BeautifulSoup(req.text, 'html.parser')
        car_name = soup.find_all(class_='vehicle-header-make-model text-truncate')
        car_price = soup.find_all(class_='heading-3 margin-y-1 font-weight-bold')
        car_km = soup.find_all('div', {'data-test': 'vehicleMileage'})

        car_name_list = []
        for i in car_name:
            car_name_list.append(i.get_text())
        # print(car_name_list)
        car_price_list = []
        for i in car_price:
            car_price_list.append(i.get_text())
        # print(car_price_list)
        car_km_list = []
        for i in car_km:
            car_km_list.append(i.get_text())
        # print(car_km_list)
        return car_name_list, car_price_list, car_km_list
    except requests.exceptions.HTTPError as err:
        raise SystemExit(err)


def Creat_db():
    try:
        cnx = mysql.connector.connect(
            host='localhost',
            user='root',
            passwd='@Farshad2825')
        cursor = cnx.cursor()
        cursor.execute('CREATE DATABASE truecar')
        print('Creat DB')
        cnx = mysql.connector.connect(
            host='localhost',
            user='root',
            passwd='@Farshad2825',
            database='truecar'
        )
        cursor = cnx.cursor()
        cursor.execute('CREATE TABLE cars (Car_Name VARCHAR(255),Car_price VARCHAR(25) ,Car_km VARCHAR(25))')
        print('Create Table')
    except mysql.connector.Error as err:
        if err.errno == errorcode.ER_ACCESS_DENIED_ERROR:
            print("Something is wrong with your user name or password")
        elif err.errno == errorcode.ER_BAD_DB_ERROR:
            print("Database does not exist")
        else:
            print(err)


def Insert_data():
    print('->')
    cnx = mysql.connector.connect(
        host='localhost',
        user='root',
        passwd='@Farshad2825',
        database='truecar'
    )
    cursor = cnx.cursor()
    Sql_comment = '''INSERT INTO cars (Car_Name,Car_price,Car_km) VALUES (%s, %s, %s)'''
    i = showdata()
    insert_rows = (i[0], i[1], i[2])
    # print(insert_rows)
    cursor.executemany(Sql_comment, insert_rows)
    print('Data Inserted')
    cnx.commit()

    Sql_comment = '''SELECT * FROM cars'''
    cursor.execute(Sql_comment)
    result = list(cursor.fetchall())
    print(result)

    cursor.close()
    cnx.close()

def showdata():
    data_ = req('acura')
    # for i in data_:
    #     print(i,'\n')
    # print(data_)
    # print(data_[1])
    # print(data_[0],data_[1],data_[2])
    # car_data=dict(zip(data_[0],zip(data_[1],data_[2])))
    # list_car_data=list(car_data.items())
    # print(car_data)
    # print(list_car_data)
    return data_


# req('acura')
# Creat_db()
Insert_data()
showdata()

在Insert_data（）函数中，我想在数据库中插入数据，并使用executemany插入列表，但我遇到了错误，确实无法解决问题 错误是：

“并非SQL语句中使用了所有参数”） mysql.connector.errors.ProgrammingError:SQL语句中未使用所有参数

执行操作失败；%s“%err” mysql.connector.errors.InterfaceError:执行操作失败；SQL语句中未使用所有参数
