python是一种面向对象的动态类型编程语言，自Guido van Rossum于1989年创立以来，已经有了整整20年的历史。的语法简洁优美，接近自然语言，数据结构与内存管理简洁明了，学习门槛低，程序调试容易，编制程序效率很高。的良好支持，拥有强大的标准库，并且可以任意扩充，这使它成为一种用途广泛的“胶水语言”。用C和C++编写高性能的函数库，并用python处理复杂的数据结构，执行函数调用，便可以做到兼顾编写效率和执行效率：编写和调试简单，执行起来也很快。
由于python学习门槛低，并可以兼顾编写效率和执行效率，令它成为广受青睐的科学计算语言。很多研究组都为python编写扩展库，以实现丰富多样的科学计算功能。但逐个配置函数库非常麻烦并且容易出错，迫切需要简化配置过程。python(x,y)是一个基于python的科学计算软件包，收集了众多的函数库以及文档、教程，并配备了可视化的程序界面和集成开发环境，非常方便科研人员使用。
python(x,y)目前的稳定版本为2.6.2，包含集成开发环境Eclipse和python开发插件pydev、数据交互式编辑和可视化工具spyder、基础数学库numpy和高级数学库scipy、3D可视化工具集MayaVi、python界面开发库PyQt、python与C/C++混合编译器SWIG，以及其他多种数学软件库，并配备了丰富齐全的帮助文档。对于水文专业应用来讲，目前尚不包含处理地理数据必须的GDAL库，正在开发中的2.6.3版本即将包含。
