...The material is organized as Jupyter notebooks so learners can work interactively and compare their answers with companion solution notebooks. Exercises cover array creation, manipulation, string operations, help utilities, input and output, and linear algebra. Additional sections address discrete Fourier transforms, logic functions, mathematics, random sampling, and set routines. Sorting, searching, counting, and statistics are also included. Rather than presenting a single application, the repository serves as a structured hands-on workbook for building practical familiarity with the NumPy API.
