说明：  本书是超过 3,000 个新闻组讨论的精华部分, 也有很多的新脚本, 涵盖了标准库的每个角落。其中每个脚本都易于理解，易于重用代码。 我有意缩短注释的长度，如果想更深入地了解背景，那么你可以参阅每个 Python 发布中的参考手册。本书的重要之处在于范例代码。
(This book is the essence of more than 3,000 newsgroup discussions. There are also many new scripts covering every corner of the standard library. Each of these scripts is easy to understand and easy to reuse code. I intend to shorten the length of the comments. If you want to get a deeper understanding of the background, then you can refer to the reference manuals in each Python release. The important part of this book is the example code.)
