price_list = [{'symbol': 'ETHBTC', 'lastPrice': '0.03574700'}, {'symbol': 'BTCUSDT', 'lastPrice': '57621.08000000'}]
print(price_list[1]['lastPrice']) # index = 1 for BTCUSDT, print 57621.08000000 => OK.
I need to get lastPrice for BTCUSDT.
Currently I can get it by index.
However, is it possible to get it by referring symbol?
Given you only have two keys which equate to identifier and value.
You could create a dict and flatten your price_list into a key value pair of symbol: lastPrice making it much easier to access the price you need via dict[symbol]
data = {k['symbol']: float(k['lastPrice']) for k in price_list}
data
#{'ETHBTC': 0.035747, 'BTCUSDT': 57621.08}
data['BTCUSDT']
#57621.08
