These PDFs are excellent for self-study, as a supplementary textbook for a course, or as a quick reference when you need to brush up on a specific algorithm's mathematical foundations.
The original authors (Press, Teukolsky, Vetterling, and Flannery) released editions in Fortran, C, and C++. Later, they published a volume simply titled Numerical Recipes in C++ . While Python is the lingua franca of modern data science, the authors never produced a dedicated "Python edition" published by Cambridge University Press.
