Jupyter Notebook is just awesome!
I was introduced to it by a colleague. We used MATLAB and struggled to get a licence because of a shortage. He already used IPython Notebook and at the time it upgraded to Jupyter Notebook he set up a server and introduced his subdivision colleagues. It spread like a wildfire in the whole R&D department. I have never seen a similar adoption and success of an open source tool or any other tool.

This experience was a game changer for me and I started using more open source software like LATEX, Blender and Inkscape. Brave Browser is the latest member of this club.

Jupyter Notebook is best used on Linux. In case you want to try it on Windows i recommend WinPython, it contains Jupyter Notebook beside some other useful tool-sets.

Even Microsoft is in love with Jupyter Notebooks! You can use them for FREE on Azure Notebooks. Microsoft uses a Linux server environment and Python 2.X, 3.X, R and F# Kernels are pre-installed.
