输出是有效的json，您可以在此处检查：https://jsonlint.com/。
答案 1 :(得分：0)
为什么不首先加载它，然后随便做什么呢？ 像这样的东西
import json
with open('./test.json','r') as f:
data = json.load(f)
s = data.replace('\t','')
s = s.replace('\n','')
s = s.replace("\'", "\"")
print(s)
答案 2 :(得分：0)
问题是您在str对象（json.load）上使用s。 load需要支持读取的文件对象。请注意，s是一个字符串，是f.read的结果。
如果要使用json.load，则需要将f放入其中。如果要从字符串加载json，请使用json.loads
data = json.loads(s)
print(data)
您还出于任何原因尝试打印s。即使结果json位于data中。
