James Powell's nearly two-hour PyData talk builds up Python's data model, decorators, generators and context managers, coding live in Vim. It aims to take intermediate programmers toward real Python expertise.
Why Hacker News points people here: HN calls it one of the best technical talks and the clearest explanation of decorators, generators and context managers.

Gives core understanding of Python's data model

I work professionally in C/C++ and the instances I needed to use Python I always felt like I was missing the core understanding of the language and was writing C in a different syntax. I found James Powell's PyData 2017 talk "So you want to be a Python expert?" ( this video ) to be incredible at helping me to gain that core understanding of the language. It's legitimately the best technical talk I think I've seen and I can't recommend it highly enough.

Explains decorators, generators, context managers and the data model

Another good (and entertaining) resource is James Powell's talk "So you want to be a Python expert" [1], the best explanation I've seen of decorators, generators and context managers. Good intro to the Python data (object) model too. [1] this video

Deep Python talk with live Vim coding

James Powell frequently gives very deep Python talks at conferences like Pydata, and shows you his coding approach in real time on Vim. Plenty of them are on YouTube and are worth a watch. This one [1] entitled "So you want to be a Python expert?" has almost half a million views! [1] this video

Understanding Python's data model improves engineering

Understanding Python's data model helped me become a better software engineer. I'd recommend watching this PyData talk (James Powell: So you want to be a Python expert? | PyData Seattle 2017 - this video ) and then using the official doc as a reference which is also fun to read: link
