4. Inventory Class with Item Management and Reporting

Write a Python class Inventory with attributes like item_id, item_name, stock_count, and price, and methods like add_item, update_item, and check_item_details.

Use a dictionary to store the item details, where the key is the item_id and the value is a dictionary containing the item_name, stock_count, and price

Sample Solution:

Python Code:

class Inventory:
    def __init__(self):
        self.inventory = {}
    def add_item(self, item_id, item_name, stock_count, price):
        self.inventory[item_id] = {"item_name": item_name, "stock_count": stock_count, "price": price}

    def update_item(self, item_id, stock_count, price):
        if item_id in self.inventory:
            self.inventory[item_id]["stock_count"] = stock_count
            self.inventory[item_id]["price"] = price
        else:
            print("Item not found in inventory.")

    def check_item_details(self, item_id):
        if item_id in self.inventory:
            item = self.inventory[item_id]
            return f"Product Name: {item['item_name']}, Stock Count: {item['stock_count']}, Price: {item['price']}"
        else:
            return "Item not found in inventory."

inventory = Inventory()

inventory.add_item("I001", "Laptop", 100, 500.00)
inventory.add_item("I002", "Mobile", 110, 450.00)
inventory.add_item("I003", "Desktop", 120, 500.00)
inventory.add_item("I004", "Tablet", 90, 550.00)
print("Item Details:")
print(inventory.check_item_details("I001"))
print(inventory.check_item_details("I002"))
print(inventory.check_item_details("I003"))
print(inventory.check_item_details("I004"))
print("\nUpdate the price of item code - 'I001':")
inventory.update_item("I001", 100, 505.00)
print(inventory.check_item_details("I001"))
print("\nUpdate the stock of item code - 'I003':")
inventory.update_item("I003", 115, 500.00)
print(inventory.check_item_details("I003"))

Sample Output:

Item Details:
Product Name: Laptop, Stock Count: 100, Price: 500.0
Product Name: Mobile, Stock Count: 110, Price: 450.0
Product Name: Desktop, Stock Count: 120, Price: 500.0
Product Name: Tablet, Stock Count: 90, Price: 550.0

Update the price of item code - 'I001':
Product Name: Laptop, Stock Count: 100, Price: 505.0

Update the stock of item code - 'I003':
Product Name: Desktop, Stock Count: 115, Price: 500.0
