The problem is that the arguments to the cursor.execute
need to be specified as one tuple, not individually.
问题在于游标的参数。执行需要指定为一个元组,而不是单独的。
Try replacing
尝试更换
cursor.execute(add_produto, va, input_date, vc)
with
与
cursor.execute(add_produto, (va, input_date, vc))

You're definately not getting some things right. Your argument list is much. This is an example:
你肯定做错了一些事情。你的论据清单很多。这是一个例子:
``import MySQLdb db=MySQLdb.connect(passwd="root",db="playful") cursor=db.cursor() use = 'python' c.execute("""SELECT the_error FROM coding WHERE tag < %s""", (use,))
