Diving In
Welcome to Python 3. Let's dive in. In this chapter, you'll install the version of Python 3 that's right for you.
Which Python Is Right For You? 哪个版本适合你
The first thing you need to do with Python is install it. Or do you?
If you're using an account on a hosted server, your ISP may have already installed Python 3. If you’re running Linux at home, you may already have Python 3, too. Most popular GNU/Linux distributions come with Python 2 in the default installation; a small but growing number of distributions also include Python 3. Mac OS X includes a command-line version of Python 2, but as of this writing it does not include Python 3. Microsoft Windows does not come with any version of Python. But don’t despair! You can point-and-click your way through installing Python, regardless of what operating system you have.让咱们自己来安装Python,无论你所用的是什么系统。
The easiest way to check for Python 3 on your Linux or Mac OS X system is to get to a command line. On Linux, look in your Applications menu for a program called Terminal. (It may be in a submenu like Accessories or System.) On Mac OS X, there is an application called Terminal.app in your /Application/Utilities/ folder.
Once you’re at a command line prompt, just type python3 (all lowercase, no spaces) and see what happens. On my home Linux system, Python 3 is already installed, and this command gets me into the Python interactive shell.
在命令行下输入 python3 ,来检查是否安装了python3

The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.

python提供了有序(sequence)类型(字符串,元组,列表都是有序类型),并且提供了特殊的语法来方便对这些类型进行操作,最常用的有切片操作。同一有序类型的对象之间支持”+”操作符,用来连成一个新的有序对象,有序对象也可以与一个整数进行相乘,得到一个新的有序对象。在调试的时候,我经常使用这样 ......
什么是pyc文件
pyc是一种二进制文件,是由py文件经过编译后,生成的文件,是一种byte code,py文件变成pyc文件后,加载的速度有所提高,而且pyc是一种跨平台的字节码,是由python的虚拟机来执行的,这个是类似于JAVA或者.NET的虚拟机的概念。pyc的内容,是跟python的版本相关的,不同版本编译后的pyc文件是不同的,2 ......
