This repo contains a few peculiar things I've learned about pandas that have made my life easier and my code faster. This post isn't a friendly tutorial for beginners, but a friendly introduction to pandas weirdness.
- pandas is column-major, which is why row-based operations are slow
SettingWithCopyWarning, or why we can't have nice things- Indexing and slicing
- Accessors
- Data exploration
- Common pitfalls
I'll continue updating this repo as I have more time. As I'm still learning pandas quirks, feedback is much appreciated.
Thanks Luke Metz, Vikram Tiwari, and Karson Elmgren for reviewing!
