This Python program helps manage a store's inventory efficiently. It provides functionalities to add, search, update, delete products, and calculate the total value of the inventory.

Features

• Add products: Allows adding new products with their name, price, and quantity.
• Search products: Search for a product by its name and view its details (price and quantity).
• Update product prices: Change the price of an existing product.
• Delete products: Remove products from the inventory.
• Calculate inventory value: Calculate the total value of all products in stock.

How It Works

• The program uses functions to handle each operation (adding, searching, updating, and deleting products).
• Products are stored in a dictionary, where the product name is the key, and the price and quantity are stored as a tuple.
• The total value of the inventory is calculated using a lambda function.

Functions

1. validate_product_name: Validates and formats product names (max 25 characters, only letters and spaces).
2. validate_product_price: Validates the product price (positive float, max 1,000,000,000).
3. validate_product_quantity: Validates the product quantity (positive integer, max 100,000,000).
4. add_product: Adds a product to the inventory if it does not already exist.
5. search_product: Searches for a product by name and displays its details.
6. update_product_price: Updates the price of an existing product.
7. delete_product: Deletes a product from the inventory.
8. menu: Displays the menu options for the user to choose from.
9. main: The main function that controls the flow of the program.

How to Use

• The program will repeatedly ask the user to select an operation until they choose to exit.
• For each operation, the user will be prompted to enter the necessary details.
• If any input is invalid, the program will ask the user to enter the correct information.
• The program calculates and displays the total inventory value when requested.

Requirements

• Python 3.x or higher.
