禅之道——http://www.pythontip.com/coding/run(python online)

本文通过Python代码实现了一种简单的字符串加密方法——ROT13,并展示了如何使用该方法来加密并显示“Python之禅”。ROT13是一种替换加密的形式,通过将字母替换为字母表中第13个位置的字母来实现加密。

code:微笑

import this

s=this.s
d = {}
for c in (65, 97):
    for i in range(26):
        d[chr(i+c)] = chr((i+13) % 26 + c)

print ('python 之禅' )

print().join([d.get(c, c) for c in s])


output:微笑

python 之禅
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!

下图是我运行以上python代码的截图(有点小bug,最后一行):
