序言

自从 Scott Meyers 撰写 Effective C++ 以来，出现了很多以 Effective 开头的书籍。
Effective 一词并不单单意味着 执行速度层面的高效率，同时还有 代码易读、易于测试
易于维护、易于扩展、易于修改和易于多人协作等理念。

目录:
  1.python风格(pythonic)
  2.函数 function  def 
  3.类与继承
  4.元类及属性，metaclass and dynamic attribute
  5.并发及并行，系统调用、子进程、C语言扩展
  6.内置模块
  7.协作开发
  8.部署，调试、优化、测试

1.python风格(pythonic)

PEP 8 风格：
 使用space(空格)来表示缩进，不要使用tab(制表符)。
 类和函数中间空两行空行。
 类内方法函数之间空一行空行。
 函数、变量、属性应该用小写字母瓶邪，个单词之间以下划线相连。
 私有类实例属性以两个下划线开头；受保护的实例属性以单个下划线开头。
 常量全部用大写字母命名。

pylint 是一款流行的python源码静态分析工具，可以检查代码是否符合PEP 8 风格
