The Zen of Python

今日まで知らなかったのだが、Pythonのインターラクティブ・モードで”import this” と入力すると、Pythonの禅の教えが表示される。読んでいると色々と面白いのであるが、その中でもNow is better than never.の文が印象に残る。後でやるというカテゴリーに入り、実行されなかったプロジェクトがいくつあることやら。。。

>>> import this
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!
