MySQLdb：操作数应包含1列

Question

我正在尝试使用Python和MySQLdb将一些数据插入MySQL数据库。当我在程序中执行以下函数时，MySQL返回错误“ 1241，'Operand应该包含1列'”

用户，密码和数据库正确，表已存在，并且授予了所有权限。

def write_to_mysql(pname, dat, like, reachs, talker, friendsfans):
''
    try:
        con = mdb.connect(user='user', passwd='password', host='localhost', db='database');
    except Exception. err:
        print(err)

    with con:

        cur = con.cursor()
        cur.execute("INSERT INTO fbinsights (page, datum, likes, reach, talking, fanfriends) VALUES( %s, %s, %s, %s, %s, %s)", (pname, dat, like, reachs, talker, friendsfans))

    connection.commit()

哪里错了？

完整回溯：

File "insights.py", line 111, in <module>
    main()
  File "insights.py", line 108, in main
    write_to_mysql(PAGE_NAME, date, likes_atm, reach_day, talking_day, friends_of_fans)
  File "insights.py", line 90, in write_to_mysql
    cur.execute("INSERT INTO fbinsights (page, datum, likes, reach, talking, fanfriends) VALUES( %s, %s, %s, %s, %s, %s)", (pname, dat, like, reachs, talker, friendsfans))

    raise errorclass, errorvalue

@schlamar回答了。错误的类型传递给MySQL。
