unescape example @ 2.17 在字符串中处理html和xml not working on Python3.9

[xiaobojiang]

Original example

s = 'Spicy "Jalapeño&quot.' from html.parser import HTMLParser p = HTMLParser() p.unescape(s) 'Spicy "Jalapeño".'

after Python 3.9, 'HTMLParser' object has no attribute 'unescape', this method is removed.

a working example of Python 3.9 : s = 'Spicy "Jalapeño&quot.' import html p = html p.unescape(s)
