Python | Get the real time currency exchange rate

Difficulty Level : Medium
Last Updated : 14 Dec, 2018

Python is a very versatile programming language. Python is being used in almost each mainstream technology and one can develop literally any application with it.

Let’s see a Python program to the real-time currency exchange rate. To use this service, one must need the API key, which can be get form here. One can get the list of currency codes from here.

We will be using CURRENCY_EXCHANGE_RATE API ,which can return the realtime exchange rate for any pair of digital currency (e.g., Bitcoin) or physical currency (e.g., USD).

Modules Needed :

requests
json

Below is the implementation :

# 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)

Output :

Result before parsing the json data :
{‘Realtime Currency Exchange Rate’: {‘1. From_Currency Code’: ‘USD’, ‘2. From_Currency Name’: ‘United States Dollar’, ‘3. To_Currency Code’: ‘INR’, ‘4. To_Currency Name’: ‘Indian Rupee’, ‘5. Exchange Rate’: ‘71.51500000’, ‘6. Last Refreshed’: ‘2018-12-13 17:40:36’, ‘7. Time Zone’: ‘UTC’}}
After parsing :
Realtime Currency Exchange Rate for United States Dollar TO Indian Rupee is 71.51500000 INR
