This new version is a TUI app built with Textual. Previous one was written using `tkinter` [0] and covered only four of the `re` functions.

Now, any valid Python expression is accepted as a solution. There are more than 100 exercises covering both the builtin `re` module and the third-party `regex` module.

These exercises have been adapted from my Understanding Python re(gex)? ebook [1] (free to read online, and PDF/EPUB versions are free till the end of this month).

See [2] for a video demo. I'd appreciate your feedback, happy learning :)
