Python之禅。

1. Beautiful is better than ugly.

优美＞丑陋

2. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated.
明了＞晦涩，简单＞复杂，复杂＞凌乱

3. Flat is better than nested.
扁平＞嵌套

4. Special cases aren‘t special enough to break the rules. Although practicality beats purity.
虽然实用性很重要，但任何特殊情况都不足以特殊到违背上述规则。（不要为了处理某一个特殊情况，而破坏了上述任何一个规则）

5. Errors should never pass silently. Unless explicitly silenced.
不要忽视任何错误，除非有意为之

6. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you‘re Dutch.
遇到模棱两可的地方，不要胡乱猜测。肯定会有一种，通常也是唯一一种，最明显的解决方案。虽然这种解决方案刚开始的时候并不是显而易见的。

7. Now is better than never. Although never is often better than *right* now.
现在开始做比不做好，但是不做比盲目去做好

8. 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.
如果一个方案难于表达，它一定是个坏的想法。如果一个方案易于表达，则它有可能是一个好的主意。
