Type:CLI
Overview
The Mini Banking System is a simple yet practical Python-based application that simulates basic banking operations such as account creation, deposit, withdrawal, balance inquiry, and transaction history. Designed with Object-Oriented Programming (OOP) principles, this CLI project helps users understand encapsulation, classes, methods, and file handling in Python.
Features
- User Authentication: Login system with username and PIN verification.
- Account Creation: Create new accounts with user details and an initial deposit.
- Deposit Funds: Add money to an account balance.
- Withdraw Funds: Withdraw money with balance checks to prevent overdrafts.
- Check Balance: View current account balance at any time.
- Transaction History: Maintain logs of deposits and withdrawals.
- Exit Option: Secure exit with optional session summary.
User Interface (CLI)
- Text-based interactive menu system with clear navigation.
- Prompt-based inputs for account actions.
- Error handling for invalid operations (e.g., insufficient balance).
- Basic terminal UI with ASCII formatting for clarity.
Example Use Case
This application serves as a foundational project for beginners learning Python OOP and file operations. It is useful for academic demonstrations, practice assignments, and conceptual understanding of how core banking functionalities work behind the scenes.
Technology Stack
- Language: Python 3.x
- Concepts Used: OOP (Classes, Objects), File Handling, Exception Handling, Lists, Dictionaries
- Optional Extension: Use JSON or SQLite for persistent storage
Benefits
- Hands-on experience with object-oriented programming in Python.
- Reinforces concepts of class-based design and data encapsulation.
- Fully offline and lightweight CLI-based solution.
- Easy to expand with additional features like interest calculation or multiple user support.
Security & Privacy
All user data is stored locally and processed securely without internet access. The PIN-based login system ensures basic account safety. Data is not shared or transmitted externally.
