python代码如何利用阿里云发送邮件

此代码是磁盘使用率超过90%就会发送邮件

#!/usr/bin/env python

#coding:utf-8

import socket

import re

import os

import smtplib

import datetime

import commands,time 

from email.mime.text import MIMEText

from email.utils import formataddr

# 硬盘使用率报警阀值

m=socket.gethostname()

s="磁盘使用率超过:"

b="测试服务器"

d="%"

hd_usage_rate_threshold = 90

def check_hd_use():

        cmd_get_hd_use = '/bin/df'

        try:

            fp = os.popen(cmd_get_hd_use)

        fp.close()

        return  hd_use
