Python类型元组不能转换为MySQL

import pymysql

# 连接数据库
conn = pymysql.connect(host='localhost', user='root', password='password', db='database_name')

# 创建游标对象
cursor = conn.cursor()

# 定义要插入的元组数据
data = ('John', 25, 'john@example.com')

# 编写SQL插入语句
sql = "INSERT INTO table_name (name, age, email) VALUES (%s, %s, %s)"

try:
    # 执行SQL语句
    cursor.execute(sql, data)
    
    # 提交事务
    conn.commit()
    print("数据插入成功！")
except Exception as e:
    # 发生错误时回滚
    conn.rollback()
    print("数据插入失败：", e)

# 关闭游标和连接
cursor.close()
conn.close()
