title: Introduction to Scientific Computation and Programming in Python
author: Daniel T. Kaplan
description: This book provides students with the modern skills and concepts needed to be able to use a computer expressively in scientific work. The authors take an integrated approach by covering programming, important methods and techniques of scientific computation (graphics, the organization of data, data acquisition, numerical issues, etc.) and the organization of software. Balancing the best of the teach-a-package and teach-a-language approaches, the book teaches general-purpose language skills and concepts, and also takes advantage of existing package-like software so that realistic computations can be performed.
