python发送邮件问题

Question

def sendEmail():
    '''send email to remind staff to remove unused data.'''
    mail_host = "smtp.qq.com"
    mail_user = "[e-mail]"
    mail_pass = "****"
    sender = "[e-mail]"
    title = "【请及时清理磁盘空间】"
    msg_txt = 'Hi all:'
    message = MIMEText(msg_txt, 'plain', 'utf-8')
    message['Subject'] = Header(title, 'utf-8')
    message['From'] = Header("***@novogene.com", 'utf-8')
    message['To'] = Header("***@novogene.com", 'utf-8')
    smtpObj = smtplib.SMTP()
    smtpObj.connect(mail_host)
    smtpObj.login(mail_user, mail_pass)
    smtpObj.sendmail(sender, '***@novogene.com', message.as_string())

    print('Email has been sent successfully!')

if __name__=='__main__':
    sendEmail()

请教这段代码python3能运行正常发邮件，python2为什么报错？谢谢
