问题描述
我一直在使用 python Alpha Vantage API 来获取有关比特币的数据，但现在我只需要获取价格。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"}}
我需要把它调到 5。
“56057.81000000”
解决方法
您需要访问 5. Exchange_Rate 键内的 Realtime Currency Exchange Rate 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
