设计模式是面对各种问题进行提炼和抽象而形成的解决方案。这些设计方案是前人不断试验,考虑了封装性、复用性、效率、可修改、可移植等各种因素的高度总结。它不限于一种特定的语言,它是一种解决问题的思想和方法 为什么要用设计模式 按照设计模式编写的代码,其可读性也会大大提升,利于团队项目的继承和扩展。 回到顶部...
AutoCAD(Autodesk Computer Aided Design)是 Autodesk(欧特克)公司首次于 1982 年开发的自动计算机辅助设计软件,在土木建筑,装饰装潢,工业制图,工程制图,电子工业,服装加工等诸多领域有着广泛的应用,主要用于二维绘图、详细绘制、设计文档和基本三维设计,现已经成为国际上广为流行的绘图工具。 上世纪 80 年代末 ...

Try to sleep on it or make a drawing of the program flow. Note: The @timer decorator is great if you just want to get an idea about the runtime of your functions. If you want to do more precise measurements of code, then you should instead consider the timeit module in the standard...
