Fetch exchange rates and log them

To fetch and log exchange rates, you’ll need to use an API like ExchangeRate API, Open Exchange Rates, or Fixer.io. Here’s a Python example using requests to fetch and log exchange rates from the ExchangeRate API:

python
CopyEdit
import requests
import logging
from datetime import datetime

# Set up logging
logging.basicConfig(filename='exchange_rates.log', level=logging.INFO, format='%(asctime)s - %(message)s')

# Replace with your actual API key and base currency
API_KEY = 'your_api_key_here'
BASE_CURRENCY = 'USD'
URL = f'https://v6.exchangerate-api.com/v6/{API_KEY}/latest/{BASE_CURRENCY}'

def fetch_and_log_exchange_rates():
    try:
        response = requests.get(URL)
        data = response.json()

        if response.status_code == 200 and data['result'] == 'success':
            rates = data['conversion_rates']
            log_entry = f"Exchange rates for {BASE_CURRENCY}: {rates}"
            logging.info(log_entry)
            print("Exchange rates logged successfully.")
        else:
            logging.error(f"Failed to fetch exchange rates: {data}")
            print("Failed to fetch exchange rates.")
    except Exception as e:
        logging.error(f"Error occurred: {e}")
        print("An error occurred while fetching exchange rates.")

fetch_and_log_exchange_rates()

Notes:

• Sign up for an API key on a service like https://www.exchangerate-api.com/.

• Schedule this script using a cron job or task scheduler to automate periodic logging.

Let me know if you want a version using another API or programming language.
