Bank Management System

This repository contains a simple Streamlit-based bank management application implemented in project1.py.

Overview

The app provides a basic banking interface for creating accounts, depositing money, withdrawing money, viewing account details, updating account information, and deleting accounts.

Features

• Create accounts with name, age, email, and PIN
• Generate a unique account number for each new account
• Store account data in data.json
• Deposit funds into an account
• Withdraw funds from an account
• View account details
• Update account name, email, or PIN
• Delete an account

File Structure

• project1.py: Main Streamlit application and bank class implementation
• data.json: JSON file used to persist account information

How It Works

• The bank class manages account data and exposes methods for account operations.
• Account data is loaded from data.json on startup and saved back after every change.
• The Streamlit UI is defined in the same file and uses sidebar navigation to select actions.

Usage

1. Install Streamlit if needed:

   pip install streamlit

2. Run the app:

   streamlit run project1.py

3. Open the provided local URL in your browser.

Notes

• The current code validates that the user must be at least 18 years old and that the PIN has exactly 4 digits.
• Deposit amounts are limited to a maximum of $10,000 and must be non-negative.
• The app uses a simple JSON file for storage, so it is best suited for demo or learning purposes rather than production use.
