This post isn't a friendly tutorial for beginners, but a friendly introduction to pandas weirdness.\n\n## What's in this repo?\n\n1. pandas is column-major, which is why row-based operations are slow\n2. `SettingWithCopyWarning`, or why we can't have nice things\n3. Indexing and slicing\n4. Accessors\n5. Data exploration\n6. Common pitfalls\n\nI'll continue updating this repo as I have more time. As I'm still learning pandas quirks, feedback is much appreciated.\n\nThanks [Luke Metz](https://twitter.com/luke_metz), [Vikram Tiwari](https://twitter.com/Vikram_Tiwari), and [Karson Elmgren](https://karsonelmgren.com/) for reviewing!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchiphuyen%2Fjust-pandas-things","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fchiphuyen%2Fjust-pandas-things","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchiphuyen%2Fjust-pandas-things/lists"}
