我在一个网站上找到了这个示例代码，并尝试根据我希望它的工作方式来实现它。不幸的是，原来的代码工作得很好，有多行被刮下的项目，但我修改的那一行只插入了1个项目。

from urllib import urlopen
from bs4 import BeautifulSoup
import pymysql.cursors

html = urlopen("https://www.banggood.com/Wholesale-Computer-and-Networking-c-155.html")

bsObj = BeautifulSoup(html, "html.parser")
recordList = bsObj.findAll("div", {"class": "wrap overflow", })

connection = pymysql.connect(host='localhost',
                             user='root',
                             password='',
                             db='db',
                             charset='utf8mb4',
                             cursorclass=pymysql.cursors.DictCursor)

try:
    with connection.cursor() as cursor:
        for record in recordList:
            title = record.find("span", {"class": 'title', }).get_text().strip()
            artist = record.find("span", {"class": "price wh_cn"}).get_text().strip()
            sql = "INSERT INTO `artist_song` (`artist`, `song`) VALUES (%s, %s)"
            cursor.execute(sql, (artist, title))
    connection.commit()
finally:
    connection.close()

我做错了什么？
