What Is Notebook?

A notebook is a web-based interactive platform for writing and running code, as well as documenting and sharing work in a variety of formats, including text, code, and graphics. It is commonly used in the fields of data science, machine learning, and scientific computing for developing and testing algorithms, analysing data, and creating visualisations.

In a notebook, users can write code in a variety of programming languages, including Python, and run it directly within the platform. The output of the code, including any visualisations or results, is displayed within the notebook alongside the code itself. This allows users to iteratively develop and test their algorithms, as well as document their work in a readable and reproducible format. Notebooks also provide a convenient platform for collaboration and sharing, as they can be easily exported and shared as files, or hosted on platforms such as Jupyter or Google Colab. This makes them a popular choice for data scientists and researchers who need to share their work with others, as well as for organisations who need to collaborate on large data projects.

Overall, notebooks provide a powerful and flexible platform for data analysis, scientific computing, and code development, making them an essential tool for many researchers and data professionals.

The format was popularised by Jupyter notebook.
