[Python] How can I pass the variable value to this string in python?

I want to assign a variable to the stop loss and take profit in the following phrase. According to the exchange documentation, these values are constants as follows(for example: 102217.88):

paramsMap = {
"symbol": symbol,
"side": side,
"positionSide": positionSide,
"type": "MARKET",
"quantity": amount,
"stopLoss": "{\"type\": \"STOP_MARKET\", \"stopPrice\": 102217.88,\"workingType\":\"MARK_PRICE\"}",
"takeProfit": "{\"type\": \"TAKE_PROFIT_MARKET\", \"stopPrice\": 102363.2178,\"price\": 102363.2178,\"workingType\":\"MARK_PRICE\"}"
}


When I use the string.format() function as below:

"stopLoss": "{\"type\": \"STOP_MARKET\", \"stopPrice\": {0},\"workingType\":\"MARK_PRICE\"}".format(str(sl)),


I get this error:

KeyError: '"type"'


So, how can I pass the sl variable value to this string?

Edit: I put the whole of my function that places an order in the exchange for more clarification.

def PlaceOrder(symbol, side, positionSide, amount, tp, sl):
payload = {}
path = '/openApi/swap/v2/trade/order'
method = "POST"
paramsMap = {
"symbol": symbol,
"side": side,
"positionSide": positionSide,
"type": "MARKET",
"quantity": amount,
"stopLoss": "{\"type\": \"STOP_MARKET\", \"stopPrice\": {},\"workingType\":\"MARK_PRICE\"}".format(str(sl)),
"takeProfit": "{\"type\": \"TAKE_PROFIT_MARKET\", \"stopPrice\": {},\"price\": 102363.2178,\"workingType\":\"MARK_PRICE\"}".format(str(tp))
}
paramsStr = request_client.parseParam(paramsMap)
response = request_client.send_request(method, path, paramsStr, payload)

return response.json()


According to JonSG's comment, I use the double {}; however, I get this error again:
