The book serves as a first introduction to computer programming of scientific applications, using the high level Python language The exposition is example and problem oriented, where the applications are taken from mathematics, numerical calculus, statistics, physics, biology and finance The book teaches Matlab style and procedural programming as well as object oriented programming High school mathematics is a required background and it is advantageous to study classical and numerical one variable calculus in parallel with reading this book Besides learning how to program computers, the reader will also learn how to solve mathematical problems, arising in various branches of science and engineering, with the aid of numerical methods and programming By blending programming, mathematics and scientific applications, the book lays a solid foundation for practicing computational science From the reviews Langtangen does an excellent job of introducing programming as a set of skills in problem solving He guides the reader into thinking properly about producing program logic and data structures for modeling real world problems using objects and functions and embracing the object oriented paradigm Summing Up Highly recommendedF H Wild III, Choice, Vol , AprilThose of us who have learned scientific programming in Python on the streets could be a little jealous of students who have the opportunity to take a course out of Langtangen s Primer John D Cook, The Mathematical Association of America, SeptemberThis book goes through Python in particular, and programming in general, via tasks that scientists will likely perform It contains valuable informationfor students new to scientific computing and would be the perfect bridge between an introduction to programming and an advanced course on numerical methods or computational scienceAlex Small, IEEE, CiSE Vol , March April This fourth edition is a wonderful, inclusive textbook that covers pretty much everything one needs to know to go from zero to fairly sophisticated scientific programming in Python Joan Horvath, Computing Reviews, March
