用ASCII字符编码字符串（查找和替换？）

Question

我有一个像下面这样的字符串：

THE SMASH-HIT, CRITICALLY ACCLAIMED SERIES RETURNS! Now that you've read the first two bestselling collections of SAGA , you're all caught up and ready to jump on the ongoing train with Chapter Thirteen, beginning an all-new monthly sci-fi/fantasy adventure, as Hazel and her parents head to the planet Quietus in search of cult romance novelist D. Oswald Heist.

它们被称为HTML entities。最简单的方法是从标准库中使用HtmlParser：

>>> s = "THE SMASH-HIT, CRITICALLY ACCLAIMED SERIES RETURNS! Now that you've read the first two bestselling collections of SAGA , you're all caught up and ready to jump on the ongoing train with Chapter Thirteen, beginning an all-new monthly sci-fi/fantasy adventure, as Hazel and her parents head to the planet Quietus in search of cult romance novelist D. Oswald Heist."
>>> import HTMLParser
>>> HTMLParser.HTMLParser().unescape(s)
u"THE SMASH-HIT, CRITICALLY ACCLAIMED SERIES RETURNS! Now that you've read the first two bestselling collections of SAGA , you're all caught up and ready to jump on the ongoing train with Chapter Thirteen, beginning an all-new monthly sci-fi/fantasy adventure, as Hazel and her parents head to the planet Quietus in search of cult romance novelist D. Oswald Heist."
