"This update to previous editions ... continues to serve as an excellent introduction to scientific programming and the Python programming language. ... Each chapter has a significant collection of exercises, which reinforce the concepts contained in the chapter. ... this is an excellent book for any individual starting to learn scientific programming, and it will serve as a great reference book for those working in the field. Summing Up: Recommended. Lower- and upper-division undergraduates." (D. B. Mason, Choice, Vol. 54 (9), May, 2017) "All the concepts are illustrated using relatively simple examples that are mostly mathematical. ... This book gives a thorough course to learn Python, and yet it is all brought at the level of a first year at the university. The fact that each concept is introduced with an example is essential. ... it is a description of how the language is used, which is a very natural approach."
