I don’t exatly know what this code could be useful for, but I think it could be useful to make something for someone. This makes you open html files or web pages with a very rough interface. I made it some time ago just to open a chrome page with cefpython with a web address. Now I added the chance to open a local file. It can navigate in folders and show python code too. Have fun.
\nPS: it works with python 3.7, not with 3.8.2. (don’t wkon with python 3.8).<\/p>\n
