Lean Python: Learn Just Enough Python to Build Useful Tools

Book Description

Learn only the essential aspects of Python without cluttering up your mind with features you may never use. This compact book is not a “best way to write code” type of book; rather, the author goes over his most-used functions, which are all you need to know as a beginner and some way beyond.

Lean Python takes 58 Python methods and functions and whittles them down to 15: as author Paul Gerrard says, “I haven’t found a need for the rest.”

What You’ll Learn

• Discover lean Python and how to learn just enough to build useful tools
• Use Python objects, program structure, I/O, modules and more
• Handle errors and exceptions
• Test your code
• Access the Web; do searching; and persist data

Who This Book Is For

This book is aimed at three categories of reader: The experienced programmer – if you already know a programming language, this book gives you a shortcut to understanding the Python language and some of its design philosophy.

You work in IT and need a programming primer – you might be a tester who needs to have more informed technical discussions with programmers. Working through the examples will help you to appreciate the challenge of good programming.

First-timer – you want a first book on programming that you can assimilate quickly to help you decide whether programming is for you.

书名：Lean Python: Learn Just Enough Python to Build Useful Tools

只学习Python的基本方面，而不是将您的脑海中塞满您可能永远不会用到的特性。这本紧凑的书不是编写代码的最佳方法类型的书；相反，作者复习了他最常用的函数，作为初学者，这些都是你需要知道的，还有一段路要走。

Lean Python 使用58个Python方法和函数，并将其缩减为15个：正如作者保罗·杰拉德所说，我还没有发现剩下的需要。

你会学到什么？

• 了解精益Python以及如何学习如何构建有用的工具
• 使用Python对象、程序结构、I/O、模块等
• 处理错误和异常
• Test your code
• 访问Web；进行搜索；持久化数据

Who This Book Is For

本书面向三类读者：有经验的程序员-如果你已经知道一门高级编程语言，这本书为你提供了一条捷径，让你更好地理解Python语言及其一些设计和哲学。

你在IT行业工作，需要一本编程入门读物–你可能是一名测试员，需要与程序员进行更有见地的技术讨论。学习这些示例将帮助您理解好的编程所面临的挑战。

初学者-你想要一本关于编程的第一本书，这样你就可以快速吸收，帮助你决定编程是否适合你。
