Python3 发送带附件的邮件 附件名如何引入变量

构建附件1,传送桌面目录下的2.txt文件

    att1 = MIMEText(open(2.txt,'rb').read(), 'base64', 'utf-8')
    att1['Content-Type'] = 'application/octet-stream'
    att1['Content-Disposition'] = 'attachment; filename = html.html'
    message.attach(att1)

怎样才能让filename = 变量.
或者附件名直接是open打开的文件名+后缀

求大佬解答

Answer 1

filename='aaa.html'
att1['Content-Disposition'] = 'attachment; filename = %s'%(filename)
