导入的依赖

import smtplib
from email.mime.text import MIMEText

给多人发送文本

import smtplib
from email.mime.text import MIMEText
# 邮箱服务器地址
mailserver = "smtp.qq.com"
# 邮箱用户名
username_send = 'XXXXX@QQ.com'
# 邮箱密码：需要使用授权码
password = 'bgqqjXXXXXXXX'
# 收件人，多个收件人用逗号隔开
username_recv = 'XXXX@qq.com,XXXX@QQ.com'
def send_email(message):
    mail = MIMEText(message)
    mail['Subject'] = '测试aaaa'
    # 发件人
    mail['From'] = username_send
    # 收件人
    mail['To'] = username_recv
    # 连接邮箱服务器，smtp的端口号是25
    smtp = smtplib.SMTP(mailserver, port=25)
    # smtp=smtplib.SMTP_SSL('smtp.qq.com',port=465)
    # #QQ邮箱的服务器和端口号
    # 登录邮箱
    smtp.login(username_send, password)
    # 参数分别是发送者，接收者，第三个是把上面的发送邮件的内容变成字符串
    smtp.sendmail(username_send, username_recv.split(','), mail.as_string())
    # 发送完毕后退出smtp
    smtp.quit()
list = ""
list += "测试"
send_email(list)
