Jupyter Notebook is an environment that holds code, execution results, equations, and explanatory text cell by cell in a single document and runs them interactively in a web browser. It uses a Python kernel by default but can attach kernels for many languages, and it is widely used for data analysis, machine learning experiments, and writing teaching materials. Documents are saved as JSON files with the .ipynb extension, and its successor interface is JupyterLab.
