Simple Banking System — Python

This project was developed as a programming exercise solved in Python to practice logic, data structures, and exception handling by simulating a basic banking management system.

About the Project

The system registers clients, processes deposits and withdrawals, generates individual account statements, and displays general statistics about all registered accounts.

The project also uses exception handling to manage invalid inputs and improve execution safety.
