如果 s 是您的数据字符串，则使用正则表达式模块：

import re
match = re.findall('data\-slug=\"()\"',str(s))

Answer 3

    from bs4 import BeautifulSoup as BS

    content = 'your html span text here'

    soup = BS(content,parser='html', features='lxml')

    dict_of_spantag_attributes_and_values = soup.span.attrs

    for i,j in dict_of_spantag_attributes_and_values.items():

        print(f'{i}:{j}')
