# just-pandas-things

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.

## What's in this repo?

1. pandas is column-major, which is why row-based operations are slow

2. `SettingWithCopyWarning`, or why we can't have nice things

3. Indexing and slicing

4. Accessors

5. Data exploration

6. Common pitfalls

I'll continue updating this repo as I have more time. As I'm still learning pandas quirks, feedback is much appreciated.
