• tkinter library (usually comes pre-installed with Python)

Setup Instructions

Step 1: Clone the repository

Clone the repository to your local machine:

git clone https://github.com/your-username/currency-converter.git
cd currency-converter

Step 2: Install dependencies

You need the requests library to fetch data from the API. Install it using pip:

pip install requests

Step 3: Get your API Key

Sign up for a free account at ExchangeRate-API and get your personal API key.

Step 4: Update the API URL

In the currency_converter.py file, replace YOUR-API-KEY with your actual API key:

self.api_url = f"https://v6.exchangerate-api.com/v6/YOUR-API-KEY/latest/USD"

Step 5: Run the application

Run the currency_converter.py script to launch the application:

python currency_converter.py

Step 6: Enjoy the app!

You can now use the app to convert between different currencies. Simply select the currencies from the dropdown, enter the amount to convert, and hit the "Convert" button.

How It Works

1. The app fetches real-time exchange rates from the ExchangeRate-API.
2. The rates are loaded dynamically into the dropdown menus for selecting the currencies to convert.
3. The user enters an amount to convert and clicks "Convert."
4. The app calculates the converted amount using the rates fetched from the API.

Troubleshooting

• 404 Error: If you see a 404 error while fetching rates, ensure that the API URL and your API key are correct.
• API Limit Exceeded: If you are using a free-tier API key, make sure you have not exceeded the rate limits. You may need to upgrade your API key for higher limits.
