  • Python之禅

    在Python的编译器中输入"import this" ,  运行后就可以得到Python之禅,它们是编写优秀Python代码的指导准则,由Tim Peters所写。

     运行结果:

    配上中文解释:

    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.
    # 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)
