Wait, what's **this**? `this` is love :heart:
等等, **this** 是什么? `this` 是爱 :heart:

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(优美的代码一定是可读的)
Special cases aren't special enough to break the rules.
没有特例特殊到需要违背这些规则(这些规则至高无上)
Although practicality beats purity.
尽管我们更倾向于实用性
Errors should never pass silently.
不要安静的包容所有错误
Unless explicitly silenced.
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.
拒绝诱惑你去猜测的暧昧事物
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.
现在行动好过永远不行动
Although never is often better than *right* now.
尽管不行动要好过鲁莽行动
If the implementation is hard to explain, it's a bad idea.
如果你无法向人描述你的方案,那肯定不是一个好方案;
If the implementation is easy to explain, it may be a good idea.
如果你能轻松向人描述你的方案,那也许会是一个好方案(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)
```
It's the Zen of Python!
这是 Python 之禅!

#### 💡 Explanation:
#### 💡 说明:
* `this` module in Python is an easter egg for The Zen Of Python ([PEP 20](https://www.python.org/dev/peps/pep-0020)).
* And if you think that's already interesting enough, check out the implementation of [this.py](https://hg.python.org/cpython/file/c3896275c0f6/Lib/this.py). Interestingly, the code for the Zen violates itself (and that's probably the only place where this happens).
* Regarding the statement `love is not True or False; love is love`, ironic but it's self-explanatory.
* `this` 模块是关于 Python 之禅的复活节彩蛋 ([PEP 20](https://www.python.org/dev/peps/pep-0020)).
* 如果你认为这已经够有趣的了, 可以看看 [this.py](https://hg.python.org/cpython/file/c3896275c0f6/Lib/this.py) 的实现. 有趣的是, Python 之禅的实现代码违反了他自己 (这可能是唯一会发生这种情况的地方).

至于 `love is not True or False; love is love`, 意外却又不言而喻.
