Are you interested in learning Python Polars? Working with Martien Lubberink PhD, I have created a fast-paced introduction to the basics here: The basics of data analysis

Why Python Polars? Because it’s a very fast “next generation data frame library” [Wes McKinney] that can handle multi-gigabyte data files with ease.

One challenge with Python has traditionally been setting things up. Please provide feedback on the (draft!) instructions here: Python Polars setup and templates

(Thanks to Konstantin Pavlenkov for providing detailed feedback on an earlier version of the materials linked to above.)

The links above now point to the maintained Python Polars chapter and its current setup instructions and templates. The reference to draft instructions is historical. The introductory chapter can be used without WRDS access; the setup page explains where to stop before the WRDS steps.
