  • Beautiful is better than ugly.

    • 优美胜于丑陋(Python以编写优美的代码为目标)
  • Explicit is better than implicit.

    • 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)
  • Simple is better than complex.

    • 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)
  • Complex is better than complicated.

    • 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)
  • Flat is better than nested.

    • 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)
  • Sparse is better than dense.

    • 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)
  • Readability counts.

    • 可读性很重要(优美的代码是可读的)
  • Special cases aren't special enough to break the rules. Although practicality beats purity.

    • 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)
  • Errors should never pass silently. Unless explicitly silenced.

    • 所有错误都不应该被直接忽略,除非能够被精确的捕获之后(其中一个典型的例子就是,不建议用Exception:pass来直接忽略所有异常。)
  • In the face of ambiguity, refuse the temptation to guess.

    • 当面对不明确的情况时,不要尝试去猜测
  • There should be one-- and preferably only one --obvious way to do it.

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

    • 虽然起初这并不那么显而易见,因为你不是 Python 之父(这里的Dutch是指Python之父Guido Van Rossum,他是荷兰人)
  • Now is better than never. Although never is often better than right now.

    • 现在行动胜过永不开始,但是不假思索就动手还不如不做(动手之前要细思量)
  • 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.

    • 如果你的实现很难向别人解释,这往往不是一个好的方案;如果你的实现很容易向别人解释,这可能是个好的方案(方案测评标准)
  • Namespaces are one honking great idea -- let's do more of those!

    • 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)
