Code a Bank Account Simulator with Python Functions

Level: Beginner

Your task for today is to build a simple bank account simulator using Python functions. This project helps you practice defining reusable functions, managing program state, and building user-interactive loops — all core programming skills.

📝 Project Task

The program should:

• Use a variable to store the current account balance.

• Define three functions:

  • deposit(amount) → adds to balance

  • withdraw(amount) → subtracts from balance (if enough funds)

  • check_balance() → prints current balance

• Show a menu in a loop with options: Deposit, Withdraw, Check Balance, Quit.

• Ask for user input, call the appropriate function, and update/display results.

Bonus (optional):

• Reject negative inputs.

• Format balance as currency.

• Track a simple transaction history.

This project is a perfect introduction to function-based design, input validation, and working with program loops.

📌 Expected Output

Example session:

If a withdrawal is greater than the balance:
