    解释:
        report_email这个函数一开始是没有的,但是这种方式好像send的接口暴露出去了,而我们的领导想的是,我不需要关心你的发送邮件接口,同时我下一次让你发送另外一种报告或者内容给其他人员,内容都不一样,你不能每次都改发邮件的send_email接口,这个接口会被改的越来越乱.你现在重新封装一个接口这个接口就是给运维人员发送,再定义一个给领导的.发送的内容以及附件都不相同.所以就出现了 report_email这个接口,只负责给运维发送邮件.给领导的内容再重新定义一个就可以了.通过这个我的大概体会是python的开放封闭原则,对发邮件本身他是封闭的,你不能动它里面的内容,而对于扩展是开放的你可以通过重新添加接口实现给种类型的人员发送邮件(感觉有种多态的意思).
