Interactive Notebooks: Marimo

Marimo is a new take on notebooks that solves some headaches of Jupyter. It runs cells reactively - when you change one cell, all dependent cells update automatically, just like a spreadsheet.

Marimo’s cells can’t be run out of order. This makes Marimo more reproducible and easier to debug, but requires a mental shift from the Jupyter/Colab way of working.

It also runs Python directly in the browser and is quite interactive. Browse the gallery of examples. With a wide variety of interactive widgets, It’s growing popular as an alternative to Streamlit for building data science web apps.

Common Operations:

# Create new notebook
uvx marimo new

# Run notebook server
uvx marimo edit notebook.py

# Export to HTML
uvx marimo export notebook.pyCopy to clipboardErrorCopied

Best Practices:

1. Cell Dependencies

   • Keep cells focused and atomic
   • Use clear variable names
   • Document data flow between cells

2. Interactive Elements

   # Add interactive widgets
   slider = mo.ui.slider(1, 100)
   # Create dynamic Markdown
   mo.md(f"{slider} {"🟢" * slider.value}")Copy to clipboardErrorCopied
   

3. Version Control

   • Keep notebooks are Python files
   • Use Git to track changes
   • Publish on marimo.app for collaboration
