+# 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
