Why does Jupyter require Python to be installed? Are there any plans to not have it as a requirement in the future?

As far as I know, JuPyteR stands for "Julia, Python and R". Yes, to run Julia and R one must first install Python to install Jupyter and the extension must end with .ipynb instead of .ijlnb or .irnb respectively.

I previously didn't know that Jupyter requires a Python installation so this suprised me.

Jupyter requires Python because Jupyter Server (serving the Notebook UI) is currently written in Python.

As for the .ipynb extension, this is mostly because Jupyter used to be the IPython notebook before. There might be some discussions on other repos for allowing for other extension names in the future.

How about the VSCode extension? Does that require Python because as far as I know extensions are written in typescript.

I hope more extensions are available in the future (while inferring the language). I would presume that this functionality wouldn't be breaking and wouldn't be hard to support.

The VS Code extension is likely using the same Jupyter Server, and therefore would need Python.

Linking to jupyter/enhancement-proposals#103 as somewhat related.
