The Python Standard Library¶ While The Python Language Reference describes the exact syntax and semantics of the Python language, this library reference manual describes the standard library that is distributed with Python. It also describes some of…
下载链接 :点我 C++ is a powerful, highly flexible, and adaptable programming language that allows software engineers to organize and process information quickly and effectively. But this high-level language is relatively difficult to master, even if you al…
A functional programming function is like a mathematical function, which produces an output that typically depends only on its arguments. Each time a functional programming function is called with the same arguments, the same result is achieved. Func…

Writing SCSS @functions is similar to writing functions in other programming languages; they can accept arguments and have return statements. SCSS provides a ton of great features, but sometimes we need to roll our own function. We can do that too! T…
“Do you pine for the nice days of Minix-1.1, when men were men and wrote their own device drivers?” Linus Torvalds Pre-requisites In order to develop Linux device drivers, it is necessary to have an understanding of the following: C programming. Some…
Guide to Python introspection https://www.ibm.com/developerworks/library/l-pyint/ Guide to Python introspection How to spy on your Python objects Published on December 01, 2002 What is introspection? In everyday life, introspection is the act of…
An application binary interface includes linkage structures for interfacing a binary application program to a digital computer. A function in a relocatable shared object module obtains the absolute address of a Global Offset Table (GOT) in the module…
Given the expansive growth in the field, it's become challenging to discern what belongs in a modern computer science degree. My own faculty is engaging in this debate, so I've coalesced my thoughts as an answer to the question, "What should every co…
有时我们需要动态生成一些模块名,然后调用它里面的函数.但是我们常常碰到的却是明明有那个模块,结果还是raise模块未定义... 我们来看看到底怎么回事? 首先我们定义一个函数 iex(1)> defmodule Science.Math do ...(1)> def add(x,y) do ...(1)> x + y ...(1)> end ...(1)> end 当我们正常调用它是,是没有问题的: iex(2)> Science.Math.add 1,2 3 但是 i…
Let’s look more closely at one of the simplest Java programs you can have—one that simply prints a message to console: public class FirstSample { public static void main(String[] args) { System.out.println("We will not use 'Hello, World!'"); } }…

In functional programming, we create large functions by composing small functions; in object-oriented programming, we create large objects by composing small objects. They are different types of composition. They might sound similar, but there is som…
Most applications on Android are developed in Java, and Android provides a rich framework of classes to support this. It is, however, also possible to develop parts of an application in native C/C++ code using the Android NDK. This is intended for ac…
