json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method
See json.dumps() as a save method and json.loads() as a retrieve method.
This is the code sample which might help you understand it more:
import json
r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

json.dumps() returns the JSON string representation of the python dict. See the docs
You can't do r['rating'] because r is a string, not a dict anymore
Perhaps you meant something like
r = {'is_claimed': 'True', 'rating': 3.5}
json = json.dumps(r) # note i gave it a different name
file.write(str(r['rating']))

How to append an dictionary into a json file?
Your problem is not appending strings/jsons to a file. Your problem is later on reading it. json files usually hold ONE json object, not many concatenated objects. You can create a list, and have you dictionaries be items in that list, and then append to it, and dump the entire list as JSON to have multiple dictionaries stored, but eventually its one JSON object. If you want to modify/append a json object in a file, you read it first, load/loads, change it however you want, and write it back. # load it with open("index.json" , "r") as json_file: file_data = json.loads(json_file.read()) # change it file_data.append(dict) # write it all back with open("index.json" , "w") as json_file: json_file.write(json.dumps(file_data)) (Obviously above code assumes you already have a list dumped as a json object in index.json) More on reddit.com

Convert JSON array to Dictionary
Hmm minda sharing an anonymized version of the file? It is hard to follow. from what i read it seems like it is a list of dictionaries and you want to merge all the dictionaries right? So from functools import reduce j = json.load(...) combined = reduce(lambda x,y: {**x, **y}, j) Explanation: Reduce takes running pairs and runs the lambda which combines dictionaries. So essentially it takes a running sum of the dictionaries to combine them. Most people like looping, but this is readable to me. For loop: ... combined = j[0] for d in j[1:]: combined = {**combined, **d} Note: in py3.9+ you can do x|y instead of {**x,**y} More on reddit.com

You can’t append to JSON files, they have to contain a single object. You can’t add a second one.

You may get the values and make dictionary out of it ,
This is what you may do
Code
d = data['response']['globalstats']['heist_success']['history']
result_dict = dict((i["date"],i["total"]) for i in d)
You may also use dict comprehension if using python version 2.7 or above
result_dict = {i["date"]:i["total"] for i in d}
Output
{1486252800: '696574',
1486339200: '357344',
1486425600: '356800',
1486512000: '311056'}

You can use a dict comprehension:
D = {h['date']:h['total'] for h in data['response']['globalstats']['heist_success']['history']}
The for will iterate over the list of dicts in history and date and total are selected as the key and value.
