How to get JSON.loads() output in dictionary type but not string type using PYTHON

Question

When I make use of JSON.dump() I am getting below JSON format

Dumps data"b'{\"AutomaticReadabilityIndex\":2.7999999999999994,\"AgeLevel\":[\" 11 to 12\"],\"Statement\":[\"Nice. Your grade is about six\"],\"SpacheScore\":1.877,\"GunningFogScore\":9.099999999999998,\"SmogIndex\":5.999999999999999}'"

When I make use of JSON.loads() I am getting below JSON format with bytes

loads data b'{"AutomaticReadabilityIndex":2.7999999999999994,"AgeLevel":[" 11 to 12"],"Statement":["Nice. Your grade is about six"],"SpacheScore":1.877,"GunningFogScore":9.099999999999998,"SmogIndex":5.999999999999999}'

My question is when I am using loads format the output has to be in dictionary type but I don't know why I am getting string type as my output. How to convert this JSON string into dictionary type.

Loads Data Type : type of loads <class 'str'>

When I trying to parse string type JSON directly I am getting below error

ERROR : Traceback (most recent call last):
File "Db.py", line 84, in <module>
print(par['GunningFogScore'])
TypeError: string indices must be integers

Answer 1

我可以简单地重现您的问题：

import json

s = {"AutomaticReadabilityIndex":2.7999999999999994,"AgeLevel":[" 11 to 12"],"Statement":["Nice. Your grade is about six"],"SpacheScore":1.877,"GunningFogScore":9.099999999999998,"SmogIndex":5.999999999999999}

print(json.dumps(json.dumps(s)))

结果：

"{\"SmogIndex\": 5.999999999999999, \"AutomaticReadabilityIndex\": 2.7999999999999994, \"SpacheScore\": 1.877, \"GunningFogScore\": 9.099999999999998, \"AgeLevel\": [\" 11 to 12\"], \"Statement\": [\"Nice. Your grade is about six\"]}"

所以要么：

• 你正在链接两个转储。第一个dump将字典转换成字符串，但是转储字符串也是有效的，所以对字符串进行转储、引号、转义等等...
• 你正在转储一个看起来像字典的字符串（"{12:1,14:2}"）。

（如果您不确定类型，请type(s)在执行转储之前检查）

所以当你重新加载时

par = json.loads(s)

你得到一个字符串，而不是字典，它解释了使用时的错误消息[]（因为你试图将键传递给字符串）

解决方法：

用于json.loads(json.loads(s))恢复您的数据。

作为更好的修复方法，只需dumps在序列化过程中使用一次即可。
