Python之禅 The Zen of Python

无论Python初学、进阶都略知Python心法一二；Python高手 、大师 一般都各种途径修习心法 熟烂于心。

所谓心法 就是The Zen of Python 。当你

心法将会向你呈现：

The Zen of Python, by Tim Peters

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

Python之禅 by Tim Peters
优美胜于丑陋
明了胜于晦涩
简洁胜于复合
复合胜于复杂
扁平胜于嵌套
分散胜于密集
可读性很重要
再特殊的情况，都不要违背规则
决不放过异常，除非确定这样做
面对模棱两可，不要尝试去猜测
尽量找一种，最好是唯一一种明确的解决方法
即使这种方法起初并不明确，除非你是荷兰人
现在开始胜过永不行动
然而仓促动手不如不做
如果实现方案很难解释，那就是个坏思路
如果实现方案容易解释，可能是个好思路
命名空间是个绝妙理念，我们应多加利用


注：Python的作者Guido是荷兰人

下面是this.py的源码  哈哈 晦涩难懂 故意复杂  可能是给The Zen of Python 做个反面案例 以供参考
