Zen of Python(Python之禅)

本文探讨了Python编程语言的设计哲学,强调了简洁、清晰和可读性的重要性。通过对比优美与丑陋、简单与复杂,文章阐述了Python为何追求简单直接的解决方案,并解释了特殊情况下如何平衡规则与实用性。

Beautiful is better than ugly. (优美比丑陋好) Explicit is better than implicit.(清晰比晦涩好) Simple is better than complex.(简单比复杂好) Complex is better than complicated.(复杂比错综复杂好) Flat is better than nested.(扁平比嵌套好) Sparse is better than dense.(稀疏比密集好) Readability counts.(可读性很重要) Special cases aren’t special enough to break the rules.(特殊情况也不应该违反这些规则) Although practicality beats purity.(但现实往往并不那么完美) Errors should never pass silently.(异常不应该被静默处理) Unless explicitly silenced.(除非你希望如此) In the face of ambiguity, refuse the temptation to guess.(遇到模棱两可的地方,不要胡乱猜测) There should be one-- and preferably only one --obvious way to do it.(肯定有一种通常也是唯一一种最佳的解决方案) Although that way may not be obvious at first unless you’re Dutch.(虽然这种方案并不是显而易见的,因为你不是那个荷兰人这里指的是Python之父Guido) Now is better than never.(现在开始做比不做好) Although never is often better than right now.(不做比盲目去做好极限编程中的YAGNI原则) If the implementation is hard to explain, it’s a bad idea.(如果一个实现方案难于理解,它就不是一个好的方案) If the implementation is easy to explain, it may be a good idea.(如果一个实现方案易于理解,它很有可能是一个好的方案) Namespaces are one honking great idea – let’s do more of those!(命名空间非常有用,我们应当多加利用)

PythonThe Zen of Python)是由Tim Peters编写的一组指导原则,用于帮助程序员更好地理解Python设计哲学,写出更优雅、简洁和易于维护的代码。 你可以通过运行以下Python代码来显示它: ```python import this ``` 以下是《Python》的内容及其简体中文翻译: 英文原文: 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! 中文翻译: 优美胜于丑陋。 明了胜于含糊。 简单胜于复杂。 复杂优于凌乱。 扁平胜于嵌套。 间隔适度比紧凑更好。 可读性很重要。 即便假借特殊之名也不能打破规则。 不过实用性优先于纯粹性。 错误绝不应悄悄忽略。 除非明确设置静默处理。 面对模棱两可之处,拒绝猜测。 应该有一种——而且最好只有一种——显而易见的做法。 尽管这种方式起初可能不明显,除非你是荷兰人。(注释:这里的“荷兰人”指代Python语言的设计者Guido van Rossum) 现在就做总好过不做。 虽然有时晚点做好过立马行动。 如果实现很难解释清楚,那肯定不是一个好主意。 若能轻松解释,则可能是不错的创意。 命名空间是个绝妙的想法 —— 让我们再多造些吧!
