1.11 禪意時刻

每種計算機語言都有自己的風格。我在前言中提到過，可以使用Python化的方式來表達自我。Python中內置了一些自由體詩歌，簡單明了地傳遞了Python的哲學（據我所知，Python是唯一一種包含這種彩蛋程序的語言）。只要在交互式解釋器中輸入import this，然后按下回車鍵就能看到如下內容：

The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
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.
Now is better than never.
Although never is often better than *right* now.
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.
Namespaces are one honking great idea--let's do more of those!

我會將這些哲學貫穿全書。
