python （18）在linux中如何实现定时发送邮件

最近要用到，定时发送邮件功能：

如何定时，当然要用到linux中crontab了

目前代码只能发邮件，能发送附件的还在学习中，稍后补上

 1 #!/usr/bin/env python
 2
 3 import smtplib
 4 from email.mime.text import MIMEText
 5 import threading
 6 import time, datetime
 7
 8 mailto_list=[""] #里面是对方的邮箱
 9 #-----------QQ邮箱发送设置----------------------
10 mail_server="smtp.qq.com"#以qq邮箱为例子，里面是QQ邮箱的服务，换成其他邮箱需要更改服务
11 mail_user=""#这是QQ邮箱的账号
12 mail_pass="这里面写上16位的编码"#直接填上密码，或者邮箱未开服务，会提醒你打开下面的链接
13 #QQ邮箱需要去官方打开服务：http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256
14 def send_mail(to_list, sub, content):
15     msg = MIMEText(content,‘plain‘,‘utf-8‘)

17     msg["Accept-Charset"]="ISO-8859-1,utf-8"
18     msg[‘Subject‘] = sub
19     msg[‘From‘] = mail_user
20     msg[‘To‘] = ";".join(to_list)
21     try:

23         server.connect(mail_server)
24         server.starttls()
25         server.login(mail_user, mail_pass)
26         server.sendmail(mail_user, to_list, msg.as_string())
27         server.close()
28         return True

31         return False

33 def getDate():
34     return str(datetime.datetime.utcfromtimestamp(time.time())+datetime.timedelta(hours=8))
