Inventory Control System

A simple Python project that simulates basic stock management operations. It integrates key programming concepts in a practical scenario.

Overview

The system allows you to:

• List all products
• Identify out-of-stock items
• Calculate total inventory value
• Filter available promotions
• Search for products with validation and error handling

Concepts Applied

• Lists, dictionaries, sets, and tuples
• Conditional logic (if, for)
• Set operations
• Exception handling (try, except, raise, finally)

How It Works

• Products are stored as a list of dictionaries (name, price, quantity)
• Out-of-stock items are collected in a set
• Total value is calculated using price × quantity (only in-stock items)
• Promotions are filtered using set difference
• User input is validated; empty input raises a ValueError, and the program always finalizes the search with finally

Example Output

--- Inventory --- Rice - $ 5.99 - 50 units ...

--- Out of Stock Products ---

• Beans
• Olive Oil

Total inventory value: $ 787.50

• Rice
• Coffee
• Pasta

Enter the product name: Rice Name: Rice | Price: $ 5.99 | Quantity: 50 --- Search completed ---
