I mean, so far, its helped make things a bit easier for me to understand. I've also read "Automate the Boring Stuff with Python" by Al Sweigart, which as someone with a non-CS background, I found very helpful, even when going back as a reference.
That's entirely plausible. The next No Starch published book I read may also be terrible. But, I try to recommend what I can (that I've read) and allow readers (present and future) to make their own judgements.
Best case scenario, you've found a new resource. Worse case scenario, you learn what works for you.
