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.<p>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.<p>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).<p>See [2] for a video demo. I'd appreciate your feedback, happy learning :)<p>[0] <a href="https://news.ycombinator.com/item?id=29391107" rel="nofollow">https://news.ycombinator.com/item?id=29391107</a><p>[1] <a href="https://github.com/learnbyexample/py_regular_expressions">https://github.com/learnbyexample/py_regular_expressions</a><p>[2] <a href="https://youtu.be/0oXPeF8HutQ" rel="nofollow">https://youtu.be/0oXPeF8HutQ</a>
