Show HN: I wrote a book on Python regular expressions

My book titled "Python re(gex)?" is free to download through this weekend [1][2]

The book covers both 're' and 'regex' modules, has plenty of examples and chapters also have cheatsheets and exercises.

Code snippets, exercises, sample chapters, etc are available on GitHub repo [3]

I used pandoc+xelatex [4] to generate the pdf.
