my_user = 'xxxxxxx@qq.com'   # 收件人邮箱账号，我这边发送给自己r


def mail():
  ret = True
  try:
    msg = MIMEText(open('a.txt', 'rb').read(), 'base64', 'utf-8')
    msg["Content-Type"] = 'application/octet-stream'
    msg["Content-Disposition"] = 'attachment; filename="a.txt"'

    msg['From']=formataddr(["xxxxx", my_sender])

     # 括号中对应的是发件人邮箱账号、收件人邮箱账号、发送邮件
    server.quit() # 关闭连接
  except Exception: # 如果 try 中的语句没有执行，则会执行下面的 ret=False
    ret = False
  return ret

ret = mail()
if ret:
  print("邮件发送成功")
