It's not a book, but the Python3 Deep Dive courses by Fred Baptiste on Udemy are very good at helping to understand the internals of python: https://www.udemy.com/user/fredbaptiste/ If the courses are pricey, remember that Udemy seems to have major sales every couple of weeks, so I'm sure they will come down in price again soon.
I'd recommend Fred Baptiste's Python Deep Dive series on Udemy:

He has 4 courses spanning 130+ hours of content covering pretty much every aspect of Python at a deep level.
