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
高级编程语言(high-level language):Python、C、C++、Perl、Java等。 低级编程语言(low-level language):有时也称“机器语言”或“汇编语言”。 高级编程语言的弱势:笼统来说,计算机只能运行低级语言编写的程序,而高级语言编写的程序需处理后才可运行。 高级编程语言的优势: 1) 简短、易读、准确性更高; 2) 灵活...
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、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...

在通常情况下,图片是否清晰是个感性认识,同一个图,有可能你觉得还过得去,而别人会觉得不清晰,缺乏一个统一的标准。然而有一些算法可以去量化图片的清晰度,做到有章可循。 原理 如果之前了解过信号处理,就会知道最直接的方法是计算图片的快速傅里叶变换,然后查看高低频分布。如果图片有少量的高频成分,那么该图片就...

Python is a general-purpose high-level computer programming language valued for its English-like syntax and powerful built-in data analysis and data science functions and libraries.
PySPH: a Python-based SPH framework PySPH is an open source framework for Smoothed Particle Hydrodynamics (SPH) simulations. It is implemented inPythonand the performance critical parts are implemented inCythonandPyOpenCL. PySPH allows users to write their high-level code in pure Python. This Python...
