准备好，我们要上路啦！
本章的唯一重点是为希望通过学习
Python
以增强自身现有技能包的网络工程
师介绍
Python
的基础概念，并非旨在为全职开发人员提供详尽的指导，使他
们能够编写生产级别的
Python
软件。
另外，要注意的是，本章所涉及的概念与
Python
之外的内容密切相关
。
例如，你只有理解了循环和数据类型等概念（稍后会讲到），才能使用
Ansible
、
Salt
、
Puppet
和
StackStorm
这些工具。

使用
Python
交互式解释器
Python
交互式解释器并不应该总是被那些刚开始学习编程，甚至是那些使用其他语言进行
开发工作的人所了解，我们认为，在尝试创建独立的可执行脚本之前，每个人都应该了解
和学习这个工具。
解释器对于各种经验水平的开发人员都发挥着重要作用。
Python
交互式解释器
，也就是通
常所说的
Python shell
，可作为初学者的学习平台
，而最有经验的开发人员也可以用它来进
行测试并获得实时反馈，无须编写完整的程序或脚本。
Python shell
，或者说解释器
，存在于大部分原生
Linux
发行版中，除此之外，很多厂商的
现代网络操作系统中也能看到它的身影，这份名单包括但不仅限于
Cisco
、
HP
、
Juniper
、
Cumulus Networks
和
Arista
。
要想进入
Python
交互式解释器
，只需打开
Linux
终端窗口或者通过
SSH
登录现代网络设
备，输入命令
python
，按
