The Zen of PythonPython 之禅#

Beautiful is better than ugly.

优美胜于丑陋。

Explicit is better than implicit.

明确胜于隐晦。

Simple is better than complex.

简单胜于复杂。

Complex is better than complicated.

复杂胜于凌乱。

Flat is better than nested.

扁平胜于嵌套。

Sparse is better than dense.

疏朗胜于稠密。

Readability counts.

可读性很重要。

Special cases aren't special enough to break the rules.

特例也没有特殊到可以打破规则。

Although practicality beats purity.

尽管实用胜过纯粹。

Errors should never pass silently.

错误绝不应悄无声息地放过。

Unless explicitly silenced.

除非明确地让它安静。

In the face of ambiguity, refuse the temptation to guess.

面对含糊，拒绝猜测的诱惑。

There should be one-- and preferably only one --obvious way to do it.

应当有一种——最好只有一种——显而易见的做法。

Although that way may not be obvious at first unless you're Dutch.

尽管这种做法起初未必显而易见，除非你是荷兰人。

Now is better than never.

现在做胜于永远不做。

Although never is often better than right now.

尽管永远不做往往胜于马上就做。

If the implementation is hard to explain, it's a bad idea.

如果实现难以解释，那它是个坏主意。

If the implementation is easy to explain, it may be a good idea.

如果实现易于解释，那它也许是个好主意。

Namespaces are one honking great idea -- let's do more of those!

命名空间是个绝妙的主意——让我们多用一些！
