I need to create a json where it takes data from variables and adds a list of object in between.

market_feed_data = scripts_df.to_list(orient="records")
no_of_records = len(scripts_df)

PAYLOAD = {
        "head": {
            "appName": APP_NAME,
            "appVer": "1.0",
            "key": USER_KEY,
            "osName": "Android",
            "requestCode": "IIFLMarRQMarketFeed",
            "userId": USER_ID,
            "password": PASSWORD,
        },
        "body": {
            "ClientCode": clientcode,
            "Count": no_of_records,
            "MarketFeedData": market_feed_data,
            "ClientLoginType": clientcode,
            "LastRequestTime": int(datetime.today().timestamp()),
            "RefreshRate": "H",
        },
    }

with above code I am able to get the json but it is adding single quotes as part of it which is making it invalid.

{'head': {'appName': 'IIFLMarSHIVANI', 'appVer': '1.0', 'key': 'N4y8B6yUcRFmPax6YrRH23wyBluqqkRY', 'osName': 'Android', 'requestCode': 'IIFLMarRQMarketFeed', 'userId': 'HYBbO7HytRE', 'password': 'G1ZqLfzAjR0'}, 'body': {'ClientCode': '92978674', 'Count': 3, 'MarketFeedData': '[{"Exch":"N","ExchType":"D","ScripCode":53699},{"Exch":"N","ExchType":"D","ScripCode":53697},{"Exch":"N","ExchType":"D","ScripCode":53697}]', 'ClientLoginType': '92978674', 'LastRequestTime': 1716294276, 'RefreshRate': 'H'}}

after this I tried creating the json using json module but could not add list arrays.

d = [53699, 53697, 53697]

no_of_records = len(d)
json_data = {}
json_data["head"] = {}
json_data["head"]["appName"] = APP_NAME
json_data["head"]["appVer"]="1.0"
json_data["head"]["key"]=USER_KEY
json_data["head"]["osName"]="Android"
json_data["head"]["requestCode"]="IIFLMarRQMarketFeed"
json_data["head"]["userId"]=USER_ID
json_data["head"]["password"]=PASSWORD
json_data["body"]={}
json_data["body"]["ClientCode"]=clientcode
json_data["body"]["Count"]=no_of_records
json_data["body"]["MarketFeedData"]=[]
json_data["body"]["ClientLoginType"]=clientcode
json_data["body"]["LastRequestTime"]=int(datetime.today().timestamp())
json_data["body"]["RefreshRate"]="H"


# json_data = json.dumps(json_data)

for i in d:
    json_data["body"]["MarketFeedData"]["Exch"]="N"
    json_data["body"]["MarketFeedData"]["ExchType"] = "D"
    json_data["body"]["MarketFeedData"]["ScripCode"] = "D"
    json_data = json.dumps(json_data)

    print(json_data)
