Show HN: Codebraid – Execute Code Blocks in Markdown (Python, Julia, Rust, R)

RMarkdown supports Python. I haven't used it, so I can't vouch for it but I have heard good things about it.

There's also jupytext, which provides round trip conversion between Rmarkdown and jupyter notebooks, so you can edit the markdown in jupyter, or in an editor and have it automatically converted to ipynb!

What are the advantages of pandoc over orgs builtin export functionality?

Yes, that's one way to describe what I'm hoping to do with this. The focus right now is on markdown, but since Pandoc supports so many input formats, it should be easy to add support for other formats like LaTeX once the markdown features stabilize. There isn't yet an equivalent of org-babel's ability to share data between code blocks, though I hope to add something similar eventually. The next big feature will probably be the ability to name code blocks, and then insert any combination of their code/output/errors at arbitrary other locations in the document.
