我有一个功能 calling insert_into_db_tmp() . 但是，当我执行它时，它使用的是完整的表示，而不是 test.com/test2 以及 path . calling insert_into_db_tmp() 声明如下：

def insert_into_db_tmp(dbcursor, table, col, val):
    try:
        query = "INSERT INTO %s (%s) VALUES (%s)",(table, ",".join(col), ",".join(val))
        print(query)
        dbcursor.execute(query)
        print("inserted!")
    except pymysql.Error as exc:
        print("error inserting...\n {}".format(exc))

我这样称呼：

connection=conn_db()
table = ['test']
col = ['path',]
val = ['test.com/test2',]
insert_into_db_tmp(connection, settings.dni+table,str(col),str(val))

当我执行这个时，我得到：

INSERT INTO test () VALUES ('{'vals': ['test.com/test2'], 'cols': ['path']}')
error inserting...
 (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'vals': ['test.com/test2'], 'cols': ['path']}')' at line 1")

注：目标 insert_into_db_tmp() 是允许多个 col 待输入，多个 val . 所以它们在未来可能会是这样的：

cols=['path','address']
vals=['somesite.com/id=6', '123 Hector Lane']

有人能帮我解决这个问题吗？
谢谢您。
