Python 发送邮件给多人

上一篇文章写了发邮件给单个人，这篇文章实现发送给多个人。

主要修改

_user = "xx@qq.com"  #发件人邮箱
_pwd = "授权码"  #发件人授权码
_recer=["aa@qq.com","bb@163.com","cc@qq.com"]  #收件人列表

import smtplib
from email.mime.text import MIMEText

_user = "xx@qq.com"
_pwd = "授权码"
# _to = "yy@163.com"
_recer=["aa@qq.com","bb@163.com","cc@qq.com"]

msg = MIMEText("今天是2021年11月16日 周二 晴天")
msg["Subject"] = " don't panic"
msg["From"] = _user
msg["To"] = ",".join(_recer)#区别与给一个人发，指定某个人用 msg["To"] = _to 多个人用.join

try:
    s=smtplib.SMTP_SSL("smtp.qq.com",465)
    s.login(_user,_pwd)
    s.sendmail(_user,_recer,msg.as_string())
    s.quit()
    print("Success!")
except smtplib.SMTPException as e:
    print("Failed,%s"%e)
