## Overview

This is a small object-oriented banking demo. Its active workflow creates a customer and current account, deposits and withdraws funds, then displays the balance and transaction history. The account base class holds balance and transaction state; current and savings accounts provide distinct account behaviors. The README is only a brief project description, so the workflow is based on the sampled source; savings-account behavior is present but not exercised by the active entry point.

Main entry points: [`main.py`](https://github.com/lokieey/bank-management/blob/main/main.py) (Demo entry point), [`current_account.py`](https://github.com/lokieey/bank-management/blob/main/current_account.py) (Current account), [`accounts.py`](https://github.com/lokieey/bank-management/blob/main/accounts.py) (Base account), [`savings_account.py`](https://github.com/lokieey/bank-management/blob/main/savings_account.py) (Savings account)
