'1行Python代碼能幹哪些事，這13個你知道嗎？'
首先你要了解一下Python之禪，一行代碼輸出“The Zen of Python”：
python -c "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!

從“The Zen of Python”也能看出，Python倡導Beautiful、Explicit、Simple等原則，當然我們接下來要介紹的一行Python能實現哪些好玩的功能，可能和Explicit原則相違背。
如果你有其他這方面的小例子，也歡迎評論，我會加到文章中，文章也許會長期更新。
