What is Jupyter Notebook?

 
Working on Jupyter Notebook is like getting into an interactive session while coding. It is an open source web-based tool for programmers; it is a sort of IDE, especially for Julia, Python, and R. The initials of these three languages form the word Jupyter. On this tool, you can code, write rich text and see the output in the form of visualization.
