Marimo

Marimo first impressions

I started to experiment with Marimo because I wanted to try a reactive notebook, that for basic data analysis seems an interesting idea.

You can check all about Marimo at marimo.io

What I like:

• the UI is polished
• it suggest to autoinstall missing packages and uses uv!

What I don’t like:

• cannot redefine variables. I have developed the habit that a notebook cell needs to be idempotent, which means that I can rerun it as many times and it still gives the same result. This does mean I can modify variables there, the most common use case is adding a column to a dataframe. With marimo I can’t do that and I need to come up with new variable names.
• doesn’t support star imports
• the ui of the dataframe seems that sometimes doesn’t sync with the data

overall it looks pretty nice, I should definitely keep playing with it.
