The author has a number of other good articles going into the depths of CPython here: https://codeconfessions.substack.com/t/cpython-internals.
One of them goes into how many lines of C it takes to execute "a + b" in Python (great explanation, but you have to go to the comments for the answer!). I remember one of my professors opening up gdb and printing every C line to execute "print("hello, world")", and the author's writings give a better understanding of what some of those lines are.
I'd be very interested in a follow-up post going in-depth on the ins and outs of list comprehension.

I started one newsletter/blog couple of months back. I write blog style posts where I write detailed articles on technical topics for example explaining the AlphaDev results from DeepMind. And I also write a links digest style post every week as well where I share some interesting articles and resources every week.

This one as well by a former intern from a decade ago who now writes on python and ml internals:
