tkinterweb 是简单又好用的 webview 组件，也可用来显示本地 html文件。
pip install tkinterweb ;
pip install readmdict ; 参见： 使用Python调用mdx字典文件进行查词
安装 MDict 去 MDict | One app for all dictionaries 下载
测试 html view 程序 tk_read_mdict.py 如下：

运行 python tk_read_mdict.py
from tkinterweb import HtmlFrame
help(HtmlFrame)

| Load a locally stored file from the specified path
