“Fluent Python” is an excellent example of a “good programming language book” — it’s not cluttered with “enterprise examples” it’s focused on how python works and goes into detail on edge cases. This lets one write code with real confidence that you know everything it’s doing. It is also written with the aim to justify *why* python is the way that it is. Which I need or I get irritated.

If you like python you should probably have a pdf or buy a copy.

Now which book on Java is analogous?
