The Zen of Python, by Tim PetersBeautiful 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.# 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）In the face of ambiguity, refuse the temptation to guess.# 当存在多种可能，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# 虽然这并不容易，因为你不是 Python 之父（这里的Dutch是指Guido）Now is better than never.Although never is often better than *right* now.# 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）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）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）
