Marimo: Revolutionizing Python Notebooks with Dataflow Graphs

Marimo is an open-source Python notebook that represents notebooks as dataflow graphs, unlike traditional REPLs. This representation blends the best of interactive computing with the reproducibility and reusability of Python software. Marimo notebooks function as reactive notebooks, executable scripts, Python modules, and interactive web apps. It addresses shortcomings of traditional notebooks in reproducibility, interactivity, maintainability, and reusability, ensuring code and output synchronization through static analysis, and supporting features like SQL embedding and module hot-reloading. Marimo is used by companies like Cloudflare, Shopify, and BlackRock.
