Python |获取实时货币汇率
原文:https://www . geesforgeks . org/python-get-the-time-currency-汇率/
Python 是一种非常通用的编程语言。几乎每种主流技术都在使用 Python，人们可以用它开发任何应用程序。
让我们看一个 Python 程序来实时计算货币汇率。要使用这个服务，必须需要 API 键，可以从这里获取。您可以在这里从获得货币代码列表。
我们将使用 CURRENCY_EXCHANGE_RATE API ，它可以返回任何一对数字货币(如比特币)或实物货币(如美元)的实时汇率。
所需模块:
requests
json
下面是实现:
# Python program to get the real-time
# currency exchange rate
# Function to get real time currency exchange
def RealTimeCurrencyExchangeRate(from_currency, to_currency, api_key) :
# importing required libraries
import requests, json
# base_url variable store base url
base_url = r"https://www.alphavantage.co/query?function = CURRENCY_EXCHANGE_RATE"
# main_url variable store complete url
main_url = base_url + "&from_currency =" + from_currency +
"&to_currency =" + to_currency + "&apikey =" + api_key
# get method of requests module
# return response object
req_ob = requests.get(main_url)
# json method return json format
# data into python dictionary data type.
# result contains list of nested dictionaries
result = req_ob.json()
print(" Result before parsing the json data :\n", result)
print("\n After parsing : \n Realtime Currency Exchange Rate for",
result["Realtime Currency Exchange Rate"]
["2\. From_Currency Name"], "TO",
result["Realtime Currency Exchange Rate"]
["4\. To_Currency Name"], "is",
result["Realtime Currency Exchange Rate"]
['5\. Exchange Rate'], to_currency)
# Driver code
if __name__ == "__main__" :
# currency code
from_currency = "USD"
to_currency = "INR"
# enter your api key here
api_key = "Your_Api_Key"
# function calling
RealTimeCurrencyExchangeRate(from_currency, to_currency, api_key)
输出:
解析 json 数据前的结果: {“实时货币汇率”:{“1。From_Currency Code': 'USD '，' 2。From_Currency Name ':'美元'，' 3。To_Currency Code': 'INR '，' 4。To_Currency Name ':'印度卢比'，' 5。汇率:' 71.51500000 '，' 6。上次刷新时间:' ' 2018-12-13 17:40:36 '，' 7。时区':' UTC'}}
解析后: 美元对印度卢比的实时货币汇率为 71.51500000 印度卢比
