 这篇文章基于PEP8，覆盖语法、模块布局、范式和架构等多个方面，介绍了一些个人认为比较好的python编写风格。
 
+原文介绍：  
+This document goes beyond PEP8 to cover the core of what I think of as great Python style. It is opinionated, but not too opinionated. It goes beyond mere issues of syntax and module layout, and into areas of paradigm, organization, and architecture. I hope it can be a kind of condensed ["Strunk & White"][strunk-white] for Python code.

 ## 遵从大部分PEP8规范
 
 PEP8涵盖了大部分用户最常用的使用内容，例如空格、函数/类/方法之间的换行符、模块的导入、针对不再被推荐的功能的警告等等，且将他们管理地非常好。
