Parse specific value from json response python

Question

I am a newbie to python and trying to get a specific value from JSON response I receive over ccxt Binance API.

I need to extract the average value and store it in a variable for further calculations

I am planning to use actualdata = (data['info']['average'])I have not yet tried the code as it requires actual order to be placed. I want to make sure that this is the correct way to parse the required data.

Also, I want to store the whole JSON response in the text file so will the below code work ("order" returns the below JSON response that I have attached) i.e passing "order" directly through json.dump

order = exchange.create_market_buy_order('ETH/USD', 0.05)
with open('orderdata/ETHUSDTorder.txt', 'w') as json_file:
    json.dump(order, json_file)
