高级语言(High-level programming language)相对于机器语言(machine language,是一种指令集的体系。这种指令集,称机器码(machine code),是电脑的CPU可直接解读的数据)而言。是高度封装了的编程语言,与低级语言相对。它是以人类的日常语言为基础的一种编程语言,使用一般人易于接受的文字来表示(例如汉字、不规则英文或其...
But in any language, you can look at the code at a high level, and say: "yeah, I recognize that design pattern." 4) Architectural level This is about the large-scale structure of your software system. At this level, the language itself doesn't much matter. An application will have ab...
1) 语法错误(syntax errors):程序的结构或结构相关的规则出错;Python对语法错误是零容忍的,一旦出错即无法执行程序。 2) 运行时错误(runtime errors):程序开始执行后出现的错误(exceptions),即发生异常。 3) 语义错误(semantic errors):程序执行成功,但并未得到预期的结果。 试验性调试(experimental debugging):调试...
1、图形化界面设计的基本理解 当前流行的计算机桌面应用程序大多数为图形化用户界面(Graphic User Interface,GUI)。 即通过鼠标对菜单、按钮等图形化元素触发指令,并从标签、对话框等图型化显示容器中获取人机对话信息。Python自带了tkinter 模块,实质上是一种流行的面向对象的GUI工具包 TK 的Python编程接口,提供了快速...
