Python JSON encoding invalid json format

Question

i've stucked, i have a json with symbols like ' in values and syntax with ' and "

Example mix double qoute and single qoutelink

json ={
 'key': "val_'_ue",
 'secondkey': 'value'
}

With json loads and json dumps i got a str type not a dict to iterate, any ideas how i get it fixed?

        print(postParams)# = {'csrf-token': "TOKEN_INCLUDES_'_'_symbols", 'param2': 'params2value'}

        jsn_dict2 = json.loads(json.dumps(postParams))
        print(type(jsn_dict2)) # ERROR HERE why str and not dict
        
        for key, val in jsn_dict2.items():
            print("key="+str(key))

json.loads converts JSON to Python; json.dumps converts Python to JSON. Using both in a chain does not make sense. — Klaus D.

From your comments to the answers it isn't clear whether res is actually JSON. Please edit the question to show its contents, or at least enough of it to provide an minimal reproducible example. — snakecharmerb

you dont need to dumps() an already string json data:

jsn_dict = json.loads(json.dumps(res))

should be :

jsn_dict = json.loads(res)

UPDATE

according to comments the data is looks like so:

postParams = "{'csrf-token': \"TOKEN_INCLUDES_'_'_symbols\", 'add-to-your-blog-submit-button': 'add-to-your-blog-submit-button'}"

so i found an library that can help damaged json string like this one:

first run :

pip install demjson
then this code can help you:

from demjson import decode
data = decode(postParams)
data
>>> {'csrf-token': "TOKEN_INCLUDES_'_'_symbols",
 'add-to-your-blog-submit-button': 'add-to-your-blog-submit-button'}

In your json u have missed the "," comma separation between two keys. The actual structure of the JSON is

json_new ={ 'key': "val_'_ue", 'secondkey': 'value' }

use

json_actual=json.dumps(json_new)

to read,

json_read=json.loads(json_actual)
