Even though it's been out for a bit now, I haven't really touched the Polars library, but that's about to change! I figure it might be a cool opportunity to showcase how I go about learning something new so I plan to livestream for 2-3 hours as I start to get more comfortable with the library. Learn some strategies and techniques that you can employ to learn new skills efficiently. Pick up some dataframe manipulation skills in the process. Hope to see you there.
