FLOSS

Free/Libre and Open Source Software, in short, FLOSS is based on the concept of a community, which itself is based on the concept of sharing, and particularly the sharing of knowledge. FLOSS are free for usage, modification and redistribution.

If you have already read this book, then you are already familiar with FLOSS since you have been using Python all along and Python is an open source software!

Here are some examples of FLOSS to give an idea of the kind of things that community sharing and building can create:

Linux

This is a FLOSS OS kernel used in the GNU/Linux operating system. Linux, the kernel, was started by Linus Torvalds as a student. Android is based on Linux. Any website you use these days will mostly be running on Linux.

Ubuntu

This is a community-driven distribution, sponsored by Canonical and it is the most popular Linux distribution today. It allows you to install a plethora of FLOSS available and all this in an easy-to-use and easy-to-install manner. Best of all, you can just reboot your computer and run GNU/Linux off the CD! This allows you to completely try out the new OS before installing it on your computer. However, Ubuntu is not entirely free software; it contains proprietary drivers, firmware, and applications.

LibreOffice

This is an excellent community-driven and developed office suite with a writer, presentation, spreadsheet and drawing components among other things. It can even open and edit MS Word and MS PowerPoint files with ease. It runs on almost all platforms and is entirely free, libre and open source software.

Mozilla Firefox

This is the best web browser. It is blazingly fast and has gained critical acclaim for its sensible and impressive features. The extensions concept allows any kind of plugins to be used.

Its companion product Thunderbird is an excellent email client that makes reading email a snap.

Mono

This is an open source implementation of the Microsoft .NET platform. It allows .NET applications to be created and run on GNU/Linux, Windows, FreeBSD, Mac OS and many other platforms as well.

Apache web server

This is the popular open source web server. In fact, it is the most popular web server on the planet! It runs nearly more than half of the websites out there. Yes, that's right - Apache handles more websites than all the competition (including Microsoft IIS) combined.

VLC Player

This is a video player that can play anything from DivX to MP3 to Ogg to VCDs and DVDs to ... who says open source ain't fun? ;-)

This list is just intended to give you a brief idea - there are many more excellent FLOSS out there, such as the Perl language, PHP language, Drupal content management system for websites, PostgreSQL database server, TORCS racing game, KDevelop IDE, Xine - the movie player, VIM editor, Quanta+ editor, Banshee audio player, GIMP image editing program, ... This list could go on forever.

简明Python3教程(A Byte of Python 3)

 关键字:[A Byte of Python v1.92(for Python 3.0)] [A Byte of Python3] 简明Python教程 Python教程 简明Python3教程    简明Python3教程<A Byte of Python3>是一本关于用Python3语言编程的书.可以作为初学这的入门教程.也可以供计算机相关人员参考. 本书可作为Python编程语言的指导或辅导.主要是针对新手的,当然,对于有经验的程序员也很有用.如果你所了解的计算机的知识就是如何保存文本文

简明Python3教程 5.第一步

介绍 我们现在来看看如何在Python中运行传统的"Hello world"程序.这会教你如何写.保存以及运行Python程序. 有两种办法来运行您的Python程序--使用交互式的解释器提示符或者源代码文件.我们现在来分别看一看这两种方法. 使用解释器提示符 在命令提示符中输入python来打开解释器. 那些在GNU/Linux与BSD上同时安装了Python 3.x与Python 2.x的用户可能需要输入python3. 而对于Windows用户而言,如果您在PATH环境变量里正确

简明Python3教程 6.基础

你肯定不满足于只打印"Hello World"吧? 你想要的更多 - 你希望得到一些输入,操纵它后再从中得到某些东西.我们可以使用python中的常量和变量实现这些功能.   字面常量(literal constant)字面常量的一个例子是数字诸如5, 1.23, 9.25e-3或字符串This is a string', "It's a string!".顾名思义,字面常量的重点在于"字面", 你直接以字面的意义使用它们.数字2永远是数字2绝不

简明Python3教程 首页

A Byte of Python 'A Byte of Python' is a free book on programming using the Python language. It serves as a tutorial or guide to the Python language for a beginner audience. If all you know about computers is how to save text files, then this is the

简明Python3教程 4.安装

如果你已经安装了Python 2.x,你不需要在安装Python 3.0前卸载Python 2.x.这两者可以共存. GNU/Linux用户和BSD用户 如果你使用类似于Ubuntu.Fedora.OpenSUSE.Debian.CentOS或其他你选择的GNU/Linux发行版,或类似于FreeBSD的BSD系统,你的系统很可能已经了Python. 可通过开启shell程序(如konsole或gnome-terminal)并输入以下命令以检测Python是否安装在你的BSD或GNU/Linux

简明Python3教程 16.标准库

简介 python标准库作为python标准安装的一部分,其自身包含数量庞大的实用模块, 因此熟悉python标准库非常重要,因为很多问题都能利用python标准库快速解决. 下面我们将研究标准库中的一些常用模块.完整的标准库模块列表可以在安装python时附带的文档中的'Library Reference'一节找到. 现在就让我们来看看这些模块吧.   提示 如果你感觉本章内容对于你过于超前,那么可以跳过本章.但是当你熟悉python编程后我强烈建议你把这章补上.   sys模块 sys模块包

简明Python3教程 9.函数

简介 函数是程序的可复用片段,允许你为语句块赋予名字之后在程序的任何地方运行它们任意次,这称做函数调用. 我们已经使用过一些内建函数,例如len和range等. 函数也许是任何有意义的软件中最重要的构件,所以我们将在本章探究函数的方方面面. 函数以关键字def定义,其后紧跟函数名,由一对小括号闭合的形参,最后以冒号结束定义行, 定义行下面的是函数体,它是一个语句块. 听着有点复杂,其实定义起来是很简单的,见下面的例子: 范例: #!/usr/bin/python # Filename: func

简明Python3教程 2.序言

Python也许是为数不多的既简单又强大的编程语言.这有利于新手甚至于专家,更重要的是用它编程所带来的乐趣. 这本书的目的是帮助您了解这种神奇的语言,展示如何快速而轻松地完成事情--事实上"编程问题的完美解决方案!" 本书的读者 本书可以作为Python编程语言的一本指南或者教程.它主要是为新手而设计,不过对于有经验的程序员来说,它同样有用. 其目的是,即使你对计算机的认识只是知道如何保存文件,你仍然可以从本书中学到的Python.如果你之前有过编程经验,你也可以从本书中学到的Pyth

简明Python3教程 14.输入输出

简介 一些情况下你不得不让程序与用户进行交互.例如,你需要从用户处得到输入然后输出计算结果.我们可以分别通过input()和print()函数做到这些. 对于输出,我们还可以使用str(string)类的各种方法.例如rjust方法可以得到一个指定宽度的右对齐字符串.详见help(str). 另一种常见的输入/输出类型为文件处理.对于很多程序拥有创建,读写文件的能力是必不可少的,我们会在这节探究这些内容.   得到用户输入 #!/usr/bin/python # user_input.py de
