昔は結構書いていたけど、最近、ブログは書かなくなってしまい、数年前に書こうと思いつつ、時間が経ってしまっている。そんな感じで書かないで時間が過ぎ去ってしまっているが、WordPressベースでここも整理したりしたので、また書いていけるようにしたいと思う今日この頃…。

Easter Eggs in Python
役に立たなそうな隠しコマンド的なやつたち。
Hello World
>>> import __hello__
Hello world!
The Zen of Python
>>> 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!
Antigravity
>>> import antigravity
Braces is Not a chance…
>>> from __future__ import braces
File "<stdin>", line 1
SyntaxError: not a chance
