Emacs + Jupyter integration got significantly better with the recent emacs-jupyter package [1], which, while young, is about as un-janky as any Elisp I've seen.

Emacs + Jupyter integration got significantly better with the recent emacs-jupyter package [1], which, while young, is about as un-janky as any Elisp I've seen. I use this daily now for Julia/Python development. The acs-jupter Org client augments Org's code cells with dynamic completion and inspection provided by the (potentially remote) kernel. The sessions can be managed per-subtree, enabling me to maintain various contexts within one Org file. [1]: https://github.com/dzop/emacs-jupyter https://github.com/dzop/emacs-jupyter
