Parsing through JSON Dict of Dicts or List of Dicts? (Python)

Question

I'm having trouble understanding whether this is a dict of dicts or a list of dicts and also how do I access keys and their corresponding values such as: 'volatility' = 29.0 or 'ask' = 11.61?

{
    "symbol": "SPY",
    "status": "SUCCESS",
    "underlying": None,
    "strategy": "SINGLE",
    "interval": 0.0,
    "isDelayed": False,
    "isIndex": False,

    "daysToExpiration": 0.0,
    "numberOfContracts": 1,
    "putExpDateMap": {

                {
                    "putCall": "PUT",
                    "symbol": "SPY_012221P390",
                    "description": "SPY Jan 22 2021 " "390 Put " "(Weekly)",
                    "exchangeName": "OPR",
                    "bid": 11.46,
                    "ask": 11.61,

                    "mark": 11.55,
                    "bidSize": 50,
                    "askSize": 50,
                    "bidAskSize": "50X50",

                    "tradeDate": None,
                    "tradeTimeInLong": 1610658217962,
                    "quoteTimeInLong": 1610658899875,
                    "netChange": 1.57,
                    "volatility": 13.012,

                    "theoreticalOptionValue": 11.628,
                    "theoreticalVolatility": 29.0,
                    "optionDeliverablesList": None,
                    "strikePrice": 390.0,
                    "expirationDate": 1611349200000,
                    "daysToExpiration": 7,
                    "expirationType": "S",
                    "lastTradingDay": 1611363600000,
                    "multiplier": 100.0,
                    "settlementType": " ",
                    "deliverableNote": "",
                    "isIndexOption": None,
                    "percentChange": 15.29,
                    "markChange": 1.28,
                    "markPercentChange": 12.47,
                    "nonStandard": False,
                    "inTheMoney": True,
                    "mini": False,
                }
            ]
        }
    },
    "callExpDateMap": {},
}

So here's the error I keep getting whenever I try to print out print(jsonDict['volatility'].json()): Hope this helps.

Traceback (most recent call last):
  File "/Users/casseroleRow/Desktop/Learning/Learning.gyp", line 26, in <module>
    print(jsonDict['volatility'].json())
TypeError: 'Response' object is not subscriptable

Well you will have to parse it like this:

jsonDict.json()['volatility'] or jsonDict.json()['putExpDateMap'].json()['2021-01-22:7'].json()['390.0'][0].json()['ask']
