I am surprised they didn't mention RMarkdown (https://rmarkdown.rstudio.com/ https://rmarkdown.rstudio.com/), which was developed in parallel to Jupyter Notebooks, with lots of convergent evolution. RMarkdown is essentially Markdown with executable code blocks. While it comes from an R background, code blocks can be written in any language (and you can mix multiple languages). The biggest difference (and, I would say, advantage) is that it separates code from output, making it work well with version control.
