If you're looking for a refresher that outlines Python language fundamentals, I recommend "Introducing Python, 2nd Edition" (2019) by Bill Lubanovic [0].

Another really cool introduction that's filled with intermediate tricks is "Python Distilled" by Dave Beazley [1] (2021).

A couple of nice intermediate books:

"Intuitive Python - Productive Development for Projects that Last" by David Muller [2] (2021).

"Serious Python" by Julien Danjou [3] (2018).
