Python Project 10: Build a Real-Time Currency Converter using API 💱🌐

📌 Problem Statement:

Create a Python script that converts one currency to another using live exchange rates from a real-time API (like ExchangeRate-API or exchangerate.host).

🧠 What You'll Learn:

• Accessing REST APIs
• Handling query parameters
• Parsing JSON responses
• Performing dynamic currency conversion

✅ Python Code:

import requests

def convert_currency(from_currency, to_currency, amount):
   url = f"https://api.exchangerate.host/convert"
   params = {
       "from": from_currency,
       "to": to_currency,
       "amount": amount
   }

   response = requests.get(url, params=params)

   if response.status_code == 200:
       data = response.json()
       converted = data['result']
       print(f"💱 {amount} {from_currency.upper()} = {converted:.2f} {to_currency.upper()}")
   else:
       print("Error fetching exchange rates.")

#Example usage
convert_currency("usd", "inr", 10)

📤 Output:

💱 10 USD = 873.54 INR

📥 How It Works:

1. Sends request with currencies and amount.
2. Fetches real-time rates from exchangerate.host.
3. Prints the converted amount clearly.

🔧 Try Modifying:

• Add input() for interactive CLI
• Support batch conversions
• Build a GUI using Tkinter

💡 Use Cases:

✅ Daily currency tracking
✅ Travel budgeting tools
✅ Financial data apps
