The Test Set by PositMarco Gorelli: Narwhals, ecosystem glue, and the value of boring workYou’ve probably used Narwhals without realizing it. It’s the compatibility layer helping apps and libraries like Plotly play nice with Pandas, Polars, Arrow, and more — while keeping computation native instead of converting everything to Pandas. In this episode, Marco Gorelli explains how his weekend experiment turned into essential ecosystem infrastructure and why data types, not APIs, are where interoperability gets tricky. Plus what it takes to build trust and community around an open-source project. Episode NotesMarco shares the Narwhals origin story (including the meme-powered name), the hard edge cases that live i...

Inspiring ComputingThe Rise of Narwhals in Open-Source In this episode of Inspiring Computing, Marco Gorelli discusses the unexpected success of Narwhals, a highly downloaded and extremely lightweight and extensible compatibility layer between data frame libraries such as pandas and polars. We dive into Marco's inspiring journey from a mathematics background to becoming a key contributor in the open-source community. Marco shares his initial struggles, motivations, and the eventual widespread adoption of narwhals. The conversation goes into the technical underpinnings of his project, from the importance of typing to robust testing techniques. He highlights collaborations, testing practices, and the challenges of maintaining backward compatibility. This episode...

The Real Python PodcastNarwhals: Expanding DataFrame Compatibility Between LibrariesHow does a Python tool support all types of DataFrames and their various features? Could a lightweight library be used to add compatibility for newer formats like Polars or PyArrow? This week on the show, we speak with Marco Gorelli about his project, Narwhals.
Narwhals is a project aimed at library maintainers rather than end users. We discuss how the added compatibility benefits users by supporting modern features like lazy evaluation. We cover several projects Marco has been working with to implement Narwhals, including Altair, scikit-lego, and Ibis.
We also discuss how Marco started contributing...

The Developers' BakeryPandas and Polars with Marco GorelliTime for a brand-new topic today here at The Developers’ Bakery: Data Science! We’re really excited to have on stage Marco Gorelli, core contributor of both pandas and polars, two of the most popular data science libraries in the Python ecosystem.
In this episode, we’ll talk about how pandas became so popular in the data science space. Then we’ll move on to talk about polars, a new data science library written in Rust, and how its performances compare to pandas.
Finally, we’ll have the opportunity to touch on a very interesting and unique...
