python使用smtplib模块发送邮件

import smtplib
import email.message

fromaddr = 'wk_helloworld@qq.com' # 账号
password = '****************'  # QQ授权码

conn = smtplib.SMTP_SSL('smtp.qq.com', 465) # 创建SMTP连接 
conn.login(fromaddr, password)    # 登录邮件服务器
msg = email.message.EmailMessage()   # 创建邮件对象
msg.set_content('您好，Python邮件')   # 设置邮件内容（普通邮件）
conn.sendmail(fromaddr, ['929667257@qq.com'], msg.as_string())  # 发送邮件

conn.quit() # 退出连接
