通过此书，你将学习：

你是否曾经希望可以从一本书里学习如何编程？如果你以前没有编程经验，你可能想知道该从哪里开始。

《深入浅出程序设计》介绍了编写计算机程序的核心概念：变量、判断、循环、函数与对象——无论运用哪种编程语言，都能在动态且多用途的Python语言中使用具体示例和练习来运用并巩固这些概念。

学习基本的工具来开始编写你感兴趣的程序，而不是其他人认为你应该使用的通用软件，并对软件能做什么(不能做什么)有一个更好的了解。当你完成这些，你就拥有了必要的基础去使用任何一种你需要或想要学习的语言或软件项目。

本书的特别之处在于：

我们认为你的时间如此宝贵以至于不应该花费在为新概念伤脑筋上面。《深入浅出程序设计》用*的认知科学和学习理论打造多感官的学习体验，运用适合大脑工作方式的直观的格式编排，而不是令人昏昏欲睡的密密麻麻的文字。

The editor saves the code you write into a file on your hard disk.The code(sometimes called the source code) is just text, and it can be written and read by humans.But computers can't process text meant for humans, at least not very well.That's why we need a tool to translate the human-friendly source code into the binary 1s and 0s that computers do understand.That's what an interpreter does.In this book,an interpreter called Python is used.

Fortunately,Python3 comes with a built-in application called IDLE,which does both jobs and more.IDLE enables you to write and edit Python code,it translates this code into binary form, and finally, it runs the Python3 program.Because of this，IDLE is known as an Integrated Development Environment.

A path refers to the set of instructions that the computer will actually follow(or excute). Your code is like a street network, with lots of sections of code connected together just like the streets in a city.When you drive through a city, you make decisions as to which streets you drive down by turning left or right at different intersections.It's the same for a program.It also needs to make decisions from time to time as to which path to take, but for your code,it is like driving along a road, it's executing a particular path.

Your program makes a decision using a branch condition.A branch condition has the value true or false.If the branch condition is true,it runs the code on the branch.And if the branch condition is false,it runs the code on the false branch.

Python uses indents to connect a sequence of commands together to form paths.So how you connect branches together?You simply indent the second branch in by one more level.(Intends matter in python.Be careful how you indent code in Python;if you don't indent your code correctly,your code might do something wildly different from what you expect.).By default IDLE idents using 4 SPACES.If you press TAB,IDLE converts it into SPACE characters.
