1.3 Jupyter Environment#

Jupyter Notebooks#

Project Jupyter is a non-profit, open-source project that aims to support interactive computing for data science and scientific computing. The project supports over 100 programming languages.

A Jupyter notebook allows you to merge text (written in Markdown, see below), images, HTML, LateX, code, and code output. It is a JSON file. The notebook is composed of cells that can be either code or text.

A Jupyter kernel is programming language-specific process that executes the code contained in a Jupyter notebook.

The cells can be run one by one. Or use the top-down menu from Run -> run all cells or Kernel -> Restart Kernel and Run All Cells

Jupyter Lab#

Jupyter Lab is an expanded version of the browser interface that includes notebooks, terminal, files (CSV, JSON etc), images, and other.

Jupyter Hub#

Is a Jupyter Lab launched by a given hardware/computer. Users may see where the computer is located in the browser address. The user may not know the type of hardware used. One exception is the selection of types of instances in public clouds.
