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
（2）程序代码：
