我有一个变量varlist，其中包含list元素，并希望将其插入我的数据库中有两列sess\u id，它是autoincrement和list，在执行此操作时，我希望在其中存储数据：

varlist=["easy"]
    cursor_one.execute("insert into data (list) values(%s)", varlist)
    conn.commit()

我的数据插入正确，但如果我增加varlist中元素的数量：

varlist=["easy","hard","medium"]
    cursor_one.execute("insert into data (list) values(%s)", varlist)
    conn.commit()

我遇到了这个错误：

Traceback (most recent call last):
     File "C:\xampp\htdocs\eclipse_workspace\Project\check.py", line 19, in 
    <module>
     cursor_one.execute("insert into data (list) values(%s)", database_list)
      File "C:\Python34\lib\site-packages\mysql\connector\cursor.py", line 
     553, in execute
     "Not all parameters were used in the SQL statement")
     mysql.connector.errors.ProgrammingError: Not all parameters were used 
     in the SQL statement

这是我的全部密码

import mysql.connector
     conn= mysql.connector.connect
    (user="root",password="",host="localhost",database="videojs")

    varlist=['easy','hard']

    cursor_one.execute("insert into data (list) values(%s)", varlist)
    conn.commit()

请帮帮我。。。。
