Jupyter Notebook (ipython Notebook)

The Jupyter Notebook (previously known as ipython Notebook) is a web-based interactive development environment, in which you can combine code execution, text and notations (markdown), mathematics, and plots. It will be run under your brrowser. The Jupyter Notebook supports a number of programming languages including Python, Julia, Octave, and R.

The Jupyter Notebook include cells. Each cell can be run independently.
You can add/remove cells, or arrange the order of them. A piece of code, or several lines of the code that we want to run together can be written in a single cell. We strongly recommend using Jupyter Notebook as a framework
