Interesting, for sure. Lots of unkind reviews on this though.
I was also struck by how many other free Python programming books (in Kindle format) there are on Amazon!
I’m no programmer, but years ago I worked with a developer that automated the web interface into a support library/technical docs I worked on.
He used Python scripts, and I occasionally “messed around” with some. A smart dude too, who could/did program in a variety of other languages.
