Filter the response from Websocket connection-CodePudding

I am attempting to filter the information from a websocket request. I can complete my request fine however the response comes back with more information than I actually require. I want to filter this information out and then use it in a variable.

For example if I just use the sample code from ByBit websocket api

import json
from websocket import create_connection

ws = create_connection("wss://stream-testnet.bybit.com/realtime")
ws.send('{"op": "subscribe", "args": ["instrument_info.100ms.BTCUSD"]}');
bybitresult = ws.recv()
print(bybitresult)
ws.close()

I get the response below

{"topic":"instrument_info.100ms.BTCUSD","type":"snapshot","data":{"id":1,"symbol":"BTCUSD","last_price_e4":192785000,"last_price":"19278.50","bid1_price_e4":192780000,"bid1_price":"19278.00","ask1_price_e4":192785000,"ask1_price":"19278.50","last_tick_direction":"ZeroPlusTick","prev_price_24h_e4":192650000,"prev_price_24h":"19265.00","price_24h_pcnt_e6":700,"high_price_24h_e4":204470000,"high_price_24h":"20447.00","low_price_24h_e4":187415000,"low_price_24h":"18741.50","prev_price_1h_e4":192785000,"prev_price_1h":"19278.50","price_1h_pcnt_e6":0,"mark_price_e4":192886700,"mark_price":"19288.67","index_price_e4":193439800,"index_price":"19343.98","open_interest":467889481,"open_value_e8":0,"total_turnover_e8":1786988413378107,"turnover_24h_e8":65984748882,"total_volume":478565052570,"volume_24h":12839296,"funding_rate_e6":-677,"predicted_funding_rate_e6":-677,"cross_seq":5562806725,"created_at":"2018-12-29T03:04:13Z","updated_at":"2022-10-25T06:09:48Z","next_funding_time":"2022-10-25T08:00:00Z","countdown_hour":2,"funding_rate_interval":8,"settle_time_e9":0,"delisting_status":"0"},"cross_seq":5562806725,"timestamp_e6":1666678189180180}

However, I only want to use some of the data within the "data" string for example 'last_price' and 'timestamp_e6'. I have attempted this by trying to split the output string but am not having any luck at the moment.

Any help would be greatly appreciated. Thank you

Convert string into dictionary, which can be achieved by using json package, so that we can get values by referring keys
