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 book describes how to use Python to develop scientific computing applications, in addition to the introduction of numerical calculation, the paper also focused on how to make interactive 2D, 3D image, how to design a sophisticated program interface, with C language of high-speed computing program, how to write a sound, such as image processing algorithm. The book relates the Python extensions include NumPy, SciPy, SymPy, Matplotlib, Traits, TraitsUI, Chaco, TVTK, Mayavi, VPython, OpenCV, involving the fields of application include numerical computation, symbolic computation, two-dimensional graphics, three-dimensional data visualization, three-dimensional animation, image processing and interface design.In the book with a large number of examples to guide readers will learn, each program has a detailed explanation, and can in the book recommended operating environment in normal operation. In addition, the book with a large number of diagrams and illustrations, and strive to reduce
