marimo-notebook

Create Python-based interactive notebooks with marimo's reactive cell architecture. marimo uses Python to create notebooks, unlike Jupyter which uses JSON. Here's an example notebook: Notice how the notebook is structured with functions can represent cell contents. Each cell is defined with the @app.cell decorator and the inputs/outputs of the function are the inputs/outputs of the cell. marimo usually takes care of the dependencies between cells automatically. Use mo.app_meta().mode == "script" to detect CLI vs interactive: Show all UI elements always. Only change the data source in script mode. Variables between cells define the reactivity of the notebook for 99% of the use-cases out there. No special state management needed. Don't mutate objects across cells (e.g., my_list.append() ); create new objects instead.
