Jupyter Notebooks are interactive, web-based computing environments that combine live code, equations, visualizations, and narrative text in a single document. They support multiple programming languages through kernels (Python, R, Julia, etc.) and are widely used for data analysis, machine learning, scientific computing, and educational purposes. Jupyter comes in two main variants: the classic Jupyter Notebook and the more modern JupyterLab, which provides a full IDE-like experience with tabbed editing, file browsers, and extensibility.
