用Python的smtplib和email来简单的发送带有附件的邮件，演示是用QQ邮箱发送，发送之前，请手动开启QQ邮箱的smtp服务器并取得授权码passWord。
具体可见知乎文章：https://zhuanlan.zhihu.com/p/33192111
使用方法：
设置好邮发送人邮箱，密码，收件人的邮箱（可以添加多个收件人）；
准备好要插入的附件（这里是图片）包括附件的路径filePath和发送过去要显示的文件名称fileName。
如：
self.sender = 'xxx@qq.com'
self.passWord = 'xxx'
self.string = 'xxx@qq.com;xxx@163.com;xxxxx@163.com'
self.filePath = '/Users/lucifer/Desktop/1.jpg'
self.fileName = 'hello.jpg'
