Not able to get the live account data by using the API

Getting Started with Alpaca
1

from alpaca.trading.client import TradingClient

from alpaca.trading.requests import GetAssetsRequest

trading_client = TradingClient(API_KEY, SECRET_KEY)

account = trading_client.get_account()

account.account_number

print(account.account_number)

I am using the above code for getting the account_numbe of my live trading account, but it only show the paper account number to me whatever I set paper=True or not.

would any one help to explain ? thanks
