我想获得任何期货资产的价格精确度。

我尝试了什么：

client.get_symbol_info(symbol='My Symbol')

但这会返回现货的精度，我需要期货的精度。

所以有这个命令：

client.futures_exchange_info()

哪个返回：

and so on.

我需要访问“quantityPrecision”的值：。

有没有办法像“BTCUSDT”这样的符号值过滤这个列表，然后返回“quantityPrecision”的值：？

在此先感谢您的帮助。

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")
