python：bottle + eel 模仿 mdict 查英汉词典
Eel 是一个轻量的 Python 库，用于制作简单的类似于离线 HTML/JS GUI 应用程序，并具有对 Python 功能和库的完全访问权限。
Eel 托管一个本地 Web 服务器，允许您使用 Python 注释函数（annotate functions），可以从 JavaScript 调用python函数，也可以从python调用JavaScript函数。
Eel 基于 Bottle 和 gevent 构建，它们提供了类似于 JavaScript 的异步事件循环。

查询英汉词典
运行 python mdict_eel.py
个人感觉：bottle + eel 比 pywebview + cef 要好用些。
