A Primer on Scientific Programming with Python (Texts in Computational Science and Engineering)

The publication serves as a primary creation to computing device programming of clinical functions, utilizing the high-level Python language. The exposition is instance and problem-oriented, the place the purposes are taken from arithmetic, numerical calculus, facts, physics, biology and finance. The ebook teaches "Matlab-style" and procedural programming in addition to object-oriented programming. highschool arithmetic is a required history and it's valuable to review classical and numerical one-variable calculus in parallel with studying this publication. in addition to studying find out how to application pcs, the reader also will the right way to resolve mathematical difficulties, coming up in quite a few branches of technological know-how and engineering, due to numerical equipment and programming. by way of mixing programming, arithmetic and clinical functions, the e-book lays a pretty good starting place for working towards computational science.

From the reviews: Langtangen … does a very good activity of introducing programming as a suite of talents in challenge fixing. He courses the reader into considering adequately approximately generating software common sense and information constructions for modeling real-world difficulties utilizing gadgets and services and embracing the object-oriented paradigm. … Summing Up: hugely recommended. 

F. H. Wild III, selection, Vol. forty seven (8), April 2010

Those folks who've realized clinical programming in Python ‘on the streets’ can be a little jealous of scholars who've the chance to take a path out of Langtangen’s Primer.” 
John D. cook dinner, The Mathematical organization of the USA, September 2011

This booklet is going via Python specifically, and programming often, through initiatives that scientists will most probably practice. It comprises useful information for scholars new to clinical computing and could be the excellent bridge among an creation to programming and a complicated path on numerical equipment or computational science.
Alex Small, IEEE, CiSE Vol. 14 (2), March/April 2012  

“This fourth version is an excellent, inclusive textbook that covers pretty well every thing one must understand to head from 0 to rather refined medical programming in Python…”
