cookbook-2nd-code is the official read-only repository containing Jupyter notebooks for the 100+ recipes in the IPython Interactive Computing and Visualization Cookbook, Second Edition by Cyrille Rossant. This software provides executable code examples demonstrating interactive computing, data analysis, and visualization techniques using IPython and Python 3.6. Users can explore practical applications across mathematics, statistics, signal processing, machine learning, and parallel computing. The code can be executed immediately in the cloud via Binder without local installation, launching a temporary server with all dependencies pre-configured. Alternatively, users may install Git and Anaconda on their local machines to clone the repository, create a dedicated conda environment using the provided configuration file, and run the notebooks locally via the Jupyter interface. While the code repository is read-only, it serves as a comprehensive companion to the published book, enabling readers to experiment with
