Answer 1

您似乎提取的文本是json对象的数组，因此只需将其括在方括号中，然后使用json库加载到dict中即可

像这样吗？

import json

text2 = '''{"@type":"Question","name":"How many COVID-19 deaths in Autauga County, Alabama?","acceptedAnswer":{"@type":"Answer","text":24}},{"@type":"Question","name":"How many COVID-19 deaths in Baldwin County, Alabama?","acceptedAnswer":{"@type":"Answer","text":46}},{"@type":"Question","name":"How many COVID-19 deaths in Barbour County, Alabama?","acceptedAnswer":{"@type":"Answer","text":7}} '''
data = json.loads('[' + text2 + ']')
for item in data:
    print(item['name'])
    print(item['acceptedAnswer']['text'])
