import pyodbc
from sqlConfig import MySQLConnectionPool

连接数据库

conn = pyodbc.connect(r’Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=D:\东和.accdb’)

创建连接池对象

ConnPool = MySQLConnectionPool()

创建游标

cursor = conn.cursor()

查询数据

cursor.execute(‘SELECT * FROM 配方列表’)

list1 = []

逐行读取数据

for row in cursor.fetchall():
list1.append(row)
print(list1)

#list = cursor.fetchall()
sql_update_one = “delete from plan_peifang_list where 1=%s”
ConnPool.update_one(sql_update_one, (1,))

我传参用list1 会报错
not enough arguments for format string，但是我用变量a就会成功。 a和变量list1的值是一样的啊？ 为什么list1会报错？
