Indepth python book/ resource

I've realised there's a lot of quirks in python like cached ints from -5 to 256, GIL preventing thread concurrency , etc. that I didn't find in online courses or books, those basically go over basic coding stuff like loops and oops.

So is there a book or something that goes in depth with how python handles memory, kernal space, system calls etc.? It gets troubling searching online for stuff, then realising later there's still stuff you missed.
