Python之禅+八荣八耻

Python之禅 (The Zen of Python):是Python语言的指导原则,可以在Python命令行输入import this显示。

The Zen of Python, by Tim Peters 

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) 

python 八荣八耻

以动手实践为荣 , 以只看不练为耻; 
以打印日志为荣 , 以单步跟踪为耻; 
以空白分隔为荣 , 以制表分隔为耻; 
以单元测试为荣 , 以手工测试为耻; 

以代码重用为荣  , 以复制粘贴为耻; 
以多态应用为荣  , 以分支判断为耻; 
以Pythonic为荣 , 以冗余拖沓为耻; 
以总结思考为荣  , 以不求甚解为耻;
