Notebooks, particularly Jupyter Notebooks, are interactive computing environments that allow users to create and share documents containing live code, equations, visualizations, and narrative text. They are widely used in data science, machine learning, and academic research for their ability to combine code execution with rich media, making them ideal for exploratory data analysis and reproducible research. Notebooks facilitate collaboration and communication among data scientists and educators by providing a platform where code and documentation coexist, enhancing understanding and engagement. Their versatility makes them valuable tools in both professional and educational settings, transforming how we approach coding and data exploration.
