今天给大伙说说python发送邮件，官方的多余的话自己去百度好了，还有一大堆文档说实话不到万不得已的时候一般人都不会去看，回归主题：
本人是mac如果没有按照依赖模块的请按照下面的截图安装
导入模块如果没有错误，表示已经安装成功。
Python发送一个未知MIME类型的文件附件其基本思路如下：
1. 构造MIMEMultipart对象做为根容器
2. 构造MIMEText对象做为邮件显示内容并附加到根容器
3. 构造MIMEBase对象做为文件附件内容并附加到根容器
a. 读入文件内容并格式化
b. 设置附件头
4. 设置根容器属性
5. 得到格式化后的完整文本
6. 用smtp发送邮件
实例代码：
1 #!/usr/bin/env python
2 # -*- coding:utf-8 -*-

5 from email.mime.multipart import MIMEMultipart
6 from email.mime.text import MIMEText

15 self.mail_host = "smtp.163.com"

22 me = self.mail_user + "<" + self.mail_user + "@" + self.mail_postfix + ">"
23 msg = MIMEMultipart()

25 msg['From'] = me
