Python3：自动发送账单邮件

Python3：自动发送账单邮件

一、前言

民间借贷，没有信用卡那样，每月会收到账单；为了民间借贷管理更加合理化，写了个还款账单小程序。

二、源码

（1）配置文件代码：

[dbmysql]
ip = localhost
port = 3306
user = root
password = ******
dbname = pythondb

[dbtime]
starttime = 220000

[dbemail]
username = ******@qq.com
password = ******
smtp = smtp.qq.com
sender = ******@qq.com
receiver = ******@qq.com

sign_company = ******
sign_addr = ******
sign_dept = ******
sign_name =******
sgin_email = ******@qq.com
sign_phone = ******
sign_qq = ******
sign_www = http://www.******.com

[dbpath]
logpath = E:logsautoemail
