🏦 Python Banking Program

A clean and interactive terminal-based Banking Program built with Python.

This project simulates basic banking operations such as login, balance checking, deposits, withdrawals, transfers, and transaction history. It is designed to demonstrate practical Python programming skills, business logic, input validation, and clean function-based code organization.
