Python连接MySQL executeemany()问题。

[Py_business124]

代码:

val=((220521,'1234567','1234567',13476123051,1100,'测试556',2,1,'521','2012-4-1'),(220522,'12345678','12345678',13476123052,522,'测试557',1,1,'522','2012-4-1'));
sql4="""insert into tdxtb_user values(%d,%s,%s,%d,%d,%s,%d,%d,%s,%s)""";
cur.executemany(sql4,val);

表字段类型依次为:int char char bigint int varchar tinyint tinyint varchar date

提示错误：少一个整形变量？！即TypeError: int argument required 可数据正好对应10个字段，是插入元组里面出错了？

何解？求高手解答！
