    pwd = '*******'          # 授权码（QQ邮箱中获取到的授权码）
    to = '*******@qq.com'    # 收件人邮箱（想要发送的人）
    sub = 'python'           # 邮箱主题（选填）
    from_n = '维维'          # 发件人昵称（选填）
    to_n = '坠梦者'          # 收件人昵称（选填）
    msg = '人生苦短，我用python'   # 发送的消息
    # 附件路径（如果想要发送附件，填入相对应的绝对路径）
    path = 'D:\\python\\help.docx'
