Zen of Python and Perl mantras

Знакомство с питоном как правило начинается с "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!
Кстати, исходный код модуля this содержит пример кодировки ROT13 ;)

У Perl-а тоже есть свои слоганы, причем автор самых известных — создатель языка:
There's more than one way to do it. — Larry Wall
Easy things should be easy, and hard things should be possible. — Larry Wall
Do what I mean.
The three principle virtues of a programmer are Laziness, Impatience, and Hubris.
If C is the Swiss Army Knife of programming languages, Perl is the Swiss Army Chainsaw.
