A Primer on Scientific Programming with Python Computing with Formulas Loops and Lists Functions and Branching Input Data and Error Handling Array Computing and Curve Plotting Files Strings and Dictionaries Introduction to Classes Random Numbers and Simple Games Object Oriented Programming Sequences and Difference Equations Introduction to Discrete Calculus. Introduction to Differential Equations A Complete Differential Equation Project Programming of Differential Equations Debugging Technical Topics Bibliography Index . 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.
