After a certain point books don't help much for learning programming. We need to either build projects of our own and for feedback we need feedback from mentors. But, in the absence of mentors, reading good code can also help.
I am looking for good quality code that is not humongous but quite readable. Like watching a carpenter carve wood, I want to read code that is well explained like Peter Norvig's pytudes: https://github.com/norvig/pytudes.
If there are channels that live code projects that are not just random youtube bros doing the same type of apps (like to-do list, etc) using some popular library, suggest them too.
Basically I am looking for good code (medium is not a constraint) that can enhance my programming skills.
