Python之禅(The Zen of Python)

Python之禅, 中英对照

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

赖勇浩 翻译

  • 优美胜于丑陋(Python 以编写优美的代码为目标)
  • 明了胜于晦涩(优美的代码应当是明了的,命名规范,风格相似)
  • 简洁胜于复杂(优美的代码应当是简洁的,不要有复杂的内部实现)
  • 复杂胜于凌乱(如果复杂不可避免,那代码间也不能有难懂的关系,要保持接口简洁)
  • 扁平胜于嵌套(优美的代码应当是扁平的,不能有太多的嵌套)
  • 间隔胜于紧凑(优美的代码有适当的间隔,不要奢望一行代码解决问题)
  • 可读性很重要(优美的代码是可读的)
  • 即便假借特例的实用性之名,也不可违背这些规则(这些规则至高无上)
  • 不要包容所有错误,除非你确定需要这样做(精准地捕获异常,不写 except:pass 风格的代码)
  • 当存在多种可能,不要尝试去猜测
  • 而是尽量找一种,最好是唯一一种明显的解决方案(如果不确定,就用穷举法)
  • 虽然这并不容易,因为你不是 Python 之父(这里的 Dutch 是指 Guido )
  • 做也许好过不做,但不假思索就动手还不如不做(动手之前要细思量)
  • 如果你无法向人描述你的方案,那肯定不是一个好方案;反之亦然(方案测评标准)
  • 命名空间是一种绝妙的理念,我们应当多加利用(倡导与号召)
