一.获取授权码

参考：http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

1. 进入qq邮箱

2. 点击设置 -- 账户，此页面往下拉，开启授权码

 按上面提示，发短信后，就可以获取到授权码

二.编写代码

# -*- coding: UTF-8 -*-
import time
import smtplib
from email.mime.text import MIMEText
from email.header import Header
#什么是授权码，它又是如何设置？ http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256
def send_email(subject, msg):
    now = time.strftime("%Y%m%d-%H-%M", time.localtime())
    # qq邮件 授权码 （改密码后会过期，需要从新获取授权码）
    pwd = "milwfffffdsssssdacg"
    # 发送方
    sender = "1970664163@qq.com"
    # 收件方
    # receivers = ["1738273291@qq.com", '1970664163@qq.com']
    receivers = ["1738273291@qq.com"]
    # 发信服务器
    smtp_server = 'smtp.qq.com'
    msg = MIMEText(msg, 'html', "utf-8")  # html格式
    msg['From'] = Header("stock web", 'utf-8') # 
    msg['To'] = Header("xiakeyun", 'utf-8')
    # 主题
    subject = f"[{now}]:{subject}"
    msg["Subject"] = Header(subject)
    # 开启发信服务，这里使用加密传输
    server = smtplib.SMTP_SSL(smtp_server)
    server.connect(smtp_server)
    # 发送邮件
    server.login(sender, pwd)
    server.sendmail(sender, receivers, msg.as_string())
    server.quit()
if __name__ == '__main__':

    send_email("测试邮件功能", "msg")

三.运行测试效果
