python设计理念，英文不错自己看。

# 输入这个语句可以看到The Zen of Python

import this The Zen of Python, by Tim Peters

Beautiful is better than ugly. 优美胜于丑陋

Explicit is better than implicit. 明了胜于晦涩

Simple is better than complex. 简单胜过复杂

Complex is better than complicated. 复杂胜过凌乱

Flat is better than nested.　　　　　扁平胜于嵌套

Sparse is better than dense. 　　　  间隔胜于紧凑

Readability counts.　　　　　　　　可读性很重要

Special cases aren't special enough to break the rules. 即使假借特例的实用性之名，也不违背这些规则

Although practicality beats purity.　　虽然实用性次于纯度

Errors should never pass silently.　　错误不应该被无声的忽略

Unless explicitly silenced.　　　　　　除非明确的沉默　　　　　　　

In the face of ambiguity, refuse the temptation to guess. 当存在多种可能时，不要尝试去猜测

There should be one-- and preferably only one --obvious way to do it. 应该有一个，最好只有一个，明显能做到这一点

Although that way may not be obvious at first unless you're Dutch. 虽然这种 方式可能不容易，除非你是python之父

Now is better than never.                                                                   现在做总比不做好

Although never is often better than *right* now.                                虽然过去从未比现在好

If the implementation is hard to explain, it's a bad idea.                     如果这个实现不容易解释，那么它肯定是坏主意

If the implementation is easy to explain, it may be a good idea.         如果这个实现容易解释，那么它很可能是个好主意

Namespaces are one honking great idea -- let's do more of those!     命名空间是一种绝妙的理念，应当多加利用 >>>
