Interesting choice of Pandas in this day and age. Maybe he’s after imparting general concepts that you could apply to any tabular data manipulator rather than selecting for the latest shiny tool.
The book is quite old actually, not sure if "this day and age" still applies to it
It was originally published in 2016, and I think this is still the first edition.
why? It's the industry standard as far as my reach goes.
What other framework would you replace it with?
No, polars or spark is not a good answer, those are optimized for data engineering performance, not a holistic approach to data science.
