It’s totally possible to decouple these if your python outputs plain JSON/csv into the data/ directory that you commit into the repo or generate just before build time. Then you can import that raw json data into an Observable .md file.

But if you want dynamically generated data at build time and want to make use of Observable’s dataloader automatic execution of data/*.json.py, for instance, while still maintaining a custom virtualenv for the project rather than your system python, you’ll need some way to specify that virtualenv’s interpreter while observable executes the build for the dev server or the full dist/ output.

So for both options it’s largely a matter of taste. I personally like using the poetry virtualenv because it’s simple to manage dependencies and the venvs in one tool, while letting me use observable’s dataloaders with third-party or custom python packages. It sounded like the parent comment wanted to use this type of approach so I focused it to that scenario specifically. I like the simplicity of the single command to generate the data and build the site.
