# 添加附件就是加上一个MIMEBase，从本地读取一个图片:
with open('''F:\data.xls''', 'rb') as f:
    # 设置附件的MIME和文件名，这里是png类型:

    # 加上必要的头信息:
    mime.add_header('Content-Disposition', 'attachment', filename='a11.xlsx')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-Id', '0')
    # 把附件的内容读进来:

    mime.set_payload(f.read())
    # 用Base64编码:
    encoders.encode_base64(mime)
    # 添加到MIMEMultipart:
    msg.attach(mime)
