Python 如何使用Alpha Vantage API获得当前价格

我一直在使用python Alpha Vantage API获取比特币的相关数据，但现在我需要的只是价格。我的代码给了我这个输出

{"Realtime Currency Exchange Rate": {"1. From_Currency Code": "BTC", "2. From_Currency Name": "Bitcoin", "3. To_Currency Code": "USD", "4. To_Currency Name": "United States Dollar", "5. Exchange Rate": "56057.81000000", "6. Last Refreshed": "2021-02-20 23:55:01", "7. Time Zone": "UTC", "8. Bid Price": "56057.50000000", "9. Ask Price": "56057.81000000"}}

我只需要把这个数增加到5

键，即：

j_obj = {"Realtime Currency Exchange Rate": {"1. From_Currency Code": "BTC", "2. From_Currency Name": "Bitcoin", "3. To_Currency Code": "USD", "4. To_Currency Name": "United States Dollar", "5. Exchange Rate": "56057.81000000", "6. Last Refreshed": "2021-02-20 23:55:01", "7. Time Zone": "UTC", "8. Bid Price": "56057.50000000", "9. Ask Price": "56057.81000000"}}

exchange_rate = j_obj["Realtime Currency Exchange Rate"]["5. Exchange Rate"]
print(exchange_rate)
# 56057.81000000
