python smtplib发送带附件邮件小程序

最近经常需要出一些临时性的报表，于是就用python 的smtplib 和email 两模块写了个小程序，当数据处理完后通过邮箱把报表文件从服务器上发送出来！

程序名称：sendMail_func.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import os
import sys
import time
import smtplib
from email import encoders
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart

def send_mail(sub,content,mail_to,fileList):
 mail_host='smtp.163.com'
 mail_user='****@163.com'
 mail_pass='******'
 mail_to_list=mail_to.split(',')

msg = MIMEMultipart()
 #msg=MIMEText(content,_charset='utf-8')
 msg['Subject']=sub
 msg['From']=mail_user
 msg['To']=";".join(mail_to_list)
 msg.attach(MIMEText(content,_charset='utf-8'))

files=fileList.split(',')
 for f in files:
   part = MIMEBase('application', 'octet-stream') #'octet-stream': binary data
   part.set_payload(open(f, 'rb').read())
   encoders.encode_base64(part)
   part.add_header('Content-Disposition', 'attachment; filename="％s"' ％ os.path.basename(f).encode('utf-8'))
   msg.attach(part)

try:
   s=smtplib.SMTP()
   s.connect(mail_host)
   s.login(mail_user,mail_pass)
   s.sendmail(mail_user,mail_to_list,msg.as_string())
   s.close()
   return True
 except Exception, e:
   print str(e)
   return False

if __name__=="__main__":
 if len(sys.argv) == 5:
   send_mail(sys.argv[1],sys.argv[2],sys.argv[3],sys.argv[4])
 else:
   print ''
   print '＊＊＊＊＊＊＊＊＊＊***************************************'
   print ' Error: 请传入四个参数值：邮件主题 邮件内容 收件人 附件路径'
   print '  如: python sendMail_func.py 邮件测试 邮件内容 abc@126.com,def@163.com,123456789@qq.com 1.xlsx,2.xlsx'
   print '＊＊＊＊＊＊＊＊＊＊***************************************'
   print ''
   exit
