python - 数据无法插入到mysql表里

问题描述

# -*- conding:utf8 -*-import tushare as tsimport pymysqltoday_data = ts.get_today_all()conn = pymysql.connect(host=’127.0.0.1’, port=3306, user=’root’, passwd=’root’, db=’test’)cursor = conn.cursor() #创建游标cursor.execute('INSERT INTO today_data(code_code,name_name,changepercent,trade,open_open,high_high,low_low,settlement,volume,turnoverratio,amount,per,pb_pb,mktcap,nmc) VALUES (’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’)',format(code_code,name_name,changepercent,trade,open_open,high_high,low_low,settlement,volume,turnoverratio,amount,per,pb_pb,mktcap,nmc))cursor.close()

上面是代码，下面是报错信息

[Getting data:]#######################################Traceback (most recent call last): File 'C:/Users/Administrator/PycharmProjects/untitled/test.py', line 7, in <module> cursor.execute('INSERT INTO today_data(code_code,name_name,changepercent,trade,open_open,high_high,low_low,settlement,volume,turnoverratio,amount,per,pb_pb,mktcap,nmc) VALUES (’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’,’{}’)',format(code_code,name_name,changepercent,trade,open_open,high_high,low_low,settlement,volume,turnoverratio,amount,per,pb_pb,mktcap,nmc))NameError: name ’code_code’ is not defined

test中是有today_data表的，表里也有这些字段，变量today_data获取到的数据也有这些字段，求指导

问题解答

异常不是提示你了么？code_code 变量没有定义
