python：PyWebIO 模仿 mdict 查英汉词典

PyWebIO提供了一系列命令式的交互函数来在浏览器上获取用户输入和进行输出，将浏览器变成了一个“富文本终端”，可以用于构建简单的Web应用或基于浏览器的GUI应用。 使用PyWebIO，开发者能像编写终端脚本一样(基于input 和 put 进行交互)来编写应用，无需具备HTML和 js的相关知识； PyWebIO还可以方便地整合进现有的Web服务。非常适合快速构建对UI要求不高的应用。

把你的词典 css文件 copy to web主目录 在 D:\Python38\Lib\site-packages\pywebio\html\

运行 python mdict_pywebio.py
