In my new pandas video, you're going to learn 25 tricks that will help you to work faster, write better code, and impress your friends. These are the most useful tricks I've learned from 5 years of teaching Python's pandas library.

Each trick is about a minute long, so you're going to learn a ton of new pandas skills in less than 30 minutes!

If you want to save these tricks for reference, you can download the Jupyter notebook from GitHub.
