IPython is an interactive computing environment that enhances the capabilities of the standard Python interpreter. It allows users to write and execute code in a more user-friendly way, providing features like syntax highlighting, auto-completion, and easy access to documentation. This makes it particularly useful for data analysis, scientific computing, and educational purposes. One of the key components of IPython is the Jupyter Notebook, which enables users to create and share documents that contain live code, equations, visualizations, and narrative text. This integration of code and documentation facilitates a more interactive and engaging learning experience, making it popular among researchers and educators.
