小白求助，python3 字典查询

请问"label所对应的的值"这句话是什么意思？

L=d["result"][0]['prediction']
for j in L:
if j['probability'] >0.9:
print(j['label'])

多谢多谢

谢谢各位前辈，按招指示已成功获取所需数据，很不幸，又出现了新问题
详情如下
d = json.loads(response.text)

for x in d["result"][0]["prediction"]:
if x["probability"]>0.8:
print(x["label"])
w = x["label"]
fi = "/var/lib/motion/" + w + ".wav"
print(fi)

执行后返回结果
mark
/var/lib/motion/jack.wav

为什么没有返回mark.wav,,
谢谢大家的帮忙

感谢lmt，lzh，
清晰准确的提示。
把这句放进去if后就没问题了，多谢

dic = {"message":"Success","result":
    [
        {"message":"Success","prediction":[
            {"label":"mark","probability":0.98014337},
            {"label":"jack","probability":0.019856641}
        ],"file":"d.jpg"}
    ]
 }

# 如果prediction 大于0.9，则打印label
for x in dic['result']:
    for y in x['prediction']:
        if y['probability'] > 0.9:
            print(y['label'])
