A Primer on Scientific Programming with Python (4th Edition) by Hans Petter Langtangen

By Hans Petter Langtangen

The e-book serves as a primary advent to desktop programming of clinical purposes, utilizing the high-level Python language. The exposition is instance and problem-oriented, the place the purposes are taken from arithmetic, numerical calculus, records, physics, biology and finance. The e-book teaches "Matlab-style" and procedural programming in addition to object-oriented programming. highschool arithmetic is a required historical past and it truly is useful to check classical and numerical one-variable calculus in parallel with interpreting this publication. in addition to studying tips on how to software desktops, the reader also will easy methods to remedy mathematical difficulties, coming up in quite a few branches of technology and engineering, because of numerical equipment and programming. by means of mixing programming, arithmetic and medical functions, the booklet lays a fantastic origin for working towards computational technological know-how.

Sample text

In fact, any assignment statement has the form of a variable name on the left-hand side and an object on the right-hand side. One may say that Python programming is about solving a problem by defining and changing objects. At this stage, you do not need to know what an object really is, just think of an int object as a collection, say a storage box, with some information about an integer number. This information is stored somewhere in the computer’s memory, and with the name C the program gets access to this information.

You will learn how to write and run a Python program, how to work with variables, how to compute with mathematical functions such as ex and sin x, and how to use Python for interactive calculations. We assume that you are somewhat familiar with computers so that you know what files and folders are, how you move between folders, how you change file and folder names, and how you write text and save it in a file. Another frequent word for folder is directory. github. com/scipro-primer. I strongly recommend you to visit this page, download and pack out the files.
