Details
When it comes to dataframes, pandas is the go-to library for many people. Yet Polars is taking the world by storm, and so many data practitioners are curious about trying it out. There is a learning curve though, as Polars introduces some concepts which pandas users might not be familiar with. This talk will be a deep dive into one of those concepts (expressions) and will focus on how you can understand them from a pandas perspective.
The lessons learned will be useful beyond Polars, as they will also enable you to use Narwhals. Narwhals is a lightweight and extensible compatibility layer between dataframe libraries which is gaining traction (Altair, Marimo, scikit-lego, and more are currently using it) - like Polars, its API is also based on expressions. By learning this concept, you will not only be able to use Polars efficiently, but you'll also know how to build dataframe-agnostic tools.
