本书介绍如何用Python开发科学计算的应用程序，除了介绍数值计算之外，还着重介绍如何制作交互式的2D、3D图像，如何设计精巧的程序界面，如 何与C语言编写的高速计算程序结合，如何编写声音、图像处理算法等内容。书中涉及的Python扩展库包括NumPy、SciPy、SymPy、 matplotlib、Traits、TraitsUI、Chaco、TVTK、Mayavi、VPython、OpenCV等，涉及的应用领域包括数值 运算、符号运算、二维图表、三维数据可视化、三维动画演示、图像处理以及界面设计等。 　　书中以大量实例引导读者逐步深入学习，每个实例程序都有详尽的解释，并都能在本书推荐的运行环境中正常运行。此外，本书附有大量的图表和插图，力求减少长篇的理论介绍和公式推导，以便读者通过实例和数据学习并掌握理论知识。

-The goal of this book is to teach computational scientists how to develop tailored, flexible, and human-efficient working environments built from small programs (scr ipts), written in the easy-to-learn, high-level language Python. The focus is on examples and applications of relevance to computational scientists: gluing existing applications and tools, e.g. for automating simulation, data analysis, and visualization　steering simulations and computational experiments　equipping old programs with graphical user interfaces　making computational Web applications　and creating interactive interfaces with a Maple/Matlab-like syntax to numerical applications in C/C++ or Fortran. In short, scr ipting with Python makes you much more productive, increases the reliability of your scientific work and lets you have more fun- on Unix, Windows and Macintosh. All the tools and examples in this book are open source codes. The second edition features new material, reorganization of text, improved example
