Not me, I read the shit out of documentation and also books like yours which distill knowledge from professionals down to a bunch of useful points. I have never not learned something (even if I knew and forgot it) from reading a good book about "Working with X".

Thanks for your hard work, and for giving it away to others gratis.

Edit: the string formatting cookbook has a ton of useful info that I always forget how to use, I'm going to bookmark your site by this page: https://mkaz.blog/working-with-python/string-formatting
