Inventory Management System

Basic Inventory Management System in Python

3. Delete Item: Removes items from the inventory.
4. View Inventory: Displays all items with their quantities and prices.
5. Search Item: Searches for a specific item in the inventory.

How to Run the Code

1. Copy the code into a Python file, e.g., inventory_management.py.
