Personal Finance Tracker

Create the Finance Tracker

Create a file named finance_tracker.py and add the following code:

pythonCopy codeimport json
import os

class FinanceTracker:
def __init__(self, filename='finance_data.json'):
    self.filename = filename
    self.transactions = self.load_data()
def load_data(self):
    if os.path.exists(self.filename):
        with open(self.filename, 'r') as file:
            return json.load(file)
    return []
def save_data(self):
    with open(self.filename, 'w') as file:
        json.dump(self.transactions, file)
def add_transaction(self, amount, category, description):
    transaction = {
        'amount': amount,
        'category': category,
        'description': description
    }
    self.transactions.append(transaction)
    self.save_data()
    print("Transaction added!")
def view_transactions(self):
    if not self.transactions:
        print("No transactions found.")
        return
    print("\nTransactions:")
    for i, transaction in enumerate(self.transactions, 1):
        print(f"{i}. {transaction['amount']} - {transaction['category']}: {transaction['description']}")
def summarize(self):
    total_income = sum(t['amount'] for t in self.transactions if t['amount'] > 0)
    total_expense = sum(t['amount'] for t in self.transactions if t['amount'] < 0)
    balance = total_income + total_expense
    print(f"\nTotal Income: {total_income}")
    print(f"Total Expense: {total_expense}")
    print(f"Balance: {balance}")
def main():
tracker = FinanceTracker()

while True:
    print("\nPersonal Finance Tracker")
    print("1. Add Transaction")
    print("2. View Transactions")
    print("3. Summarize")
    print("4. Exit")
    
    choice = input("Choose an option (1-4): ")
    if choice == '1':
        amount = float(input("Enter the transaction amount (use negative for expenses): "))
        category = input("Enter the transaction category: ")
        description = input("Enter a description: ")
        tracker.add_transaction(amount, category, description)
    elif choice == '2':
        tracker.view_transactions()
    elif choice == '3':
        tracker.summarize()
    elif choice == '4':
        print("Exiting the tracker.")
        break
    else:
        print("Invalid choice. Please try again.")
if __name__ == "__main__":
main()

Step 2: Running the Finance Tracker

2. Navigate to the directory where you saved finance_tracker.py.
3. Run the script using the command:bashCopy codepython finance_tracker.py

Features of the Tracker

• Add Transaction: You can add income or expense transactions. Income should be entered as a positive amount, while expenses should be negative.
• View Transactions: Displays all recorded transactions with their details.
• Summarize: Provides a summary of total income, total expenses, and the overall balance.
• Data Persistence: Transactions are saved in a JSON file (finance_data.json) so that you can access them even after closing the application.
