Binance API: How do I get the quantity precision of a futures asset?

Question

I want to get the price precision of any futures asset.

What I tried:

client.get_symbol_info(symbol='My Symbol')

But this returns the precision of the Spot and I need the precision of the futures.

So theres this Command:

client.futures_exchange_info()

Which return this:

{'timezone': 'UTC', 'serverTime': 1630437033153, 'futuresType': 'U_MARGINED', 'rateLimits': [{'rateLimitType': 'REQUEST_WEIGHT', 'interval': 'MINUTE', 'intervalNum': 1, 'limit': 2400},

{'rateLimitType': 'ORDERS', 'interval': 'MINUTE', 'intervalNum': 1, 'limit': 1200},

{'rateLimitType': 'ORDERS', 'interval': 'SECOND', 'intervalNum': 10, 'limit': 300}],

'exchangeFilters': [],

'assets': [{'asset': 'USDT', 'marginAvailable': True, 'autoAssetExchange': '-10000'},

{'asset': 'BTC', 'marginAvailable': True, 'autoAssetExchange': '-0.00100000'},

{'asset': 'BNB', 'marginAvailable': True, 'autoAssetExchange': '-10'},

{'asset': 'ETH', 'marginAvailable': True, 'autoAssetExchange': '-5'},

{'asset': 'BUSD', 'marginAvailable': True, 'autoAssetExchange': '-10000'}],

and so on.

I need to access the Value of 'quantityPrecision':.

Is there a way to like filter this list for the symbol value like 'BTCUSDT' and then return the Value of 'quantityPrecision':?

Thanks in Advance for any help.

info = client.futures_exchange_info()
    
def get_precision(symbol):
   for x in info['symbols']:
    if x['symbol'] == symbol:
        return x['quantityPrecision']

print(get_precision('LTCUSDT'))

async function getLimits(asset) {
    var filtered = await client.futures_exchange_info()
    return Object.values( filtered.symbols).filter(O => O.symbol===asset)[0]
}

getLimits("BTCUSDT")
