python語言之父對python設計之初提出了規范和風格，名為“Pythonic"，它指的是以Python的方式去編寫代碼、組織邏輯和對象行為。更久以后你才會真正理解它的含義，你可以從PEP中了解，也可以在Python解析器中輸入import this回車查看。

>>> import thisThe Zen of Python, by Tim PetersBeautiful 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!

大致翻譯一下：

優美勝于丑陋， 明了勝于晦澀。 簡潔勝于復雜， 復雜勝于凌亂。 扁平勝于嵌套， 稀疏勝于密繁。 可讀性很重要！ 即便假借特例的實用性之名，也不可違背這些規則。 不要放過一切錯誤，除非錯誤本身需要以忽略對待。 不確定面前，我們應抵擋妄加猜測的引誘。 應該有一種，也但愿只有這一種是顯而易見的解決之道。 萬事開頭難，除非荷蘭人。 做好過不做，而不假思索就動手還不如不做。 如果某個實現無法很好闡釋，那么它肯定是一個糟糕的辦法； 如果某個實現很容易說清楚，那么它可能就是個不錯的方案。 命名空間是個絕妙的發明——對此我們應多多益善！
