Answer 1

class Product:

    products__count = 0

    def __init__(self, id, name):
        self.product__id = id
        self.product__name = name
        Product.products__count += 1

    def __del__(self):
        print(f'Product deleted ({self.product__name})')
        Product.products__count -= 1

        if Product.products__count == 0:
            print('Product is out of stock')

    def changeDataProduct(self, new__id, new__name):
        self.product__id = new__id
        self.product__name = new__name
        print('Data changed')

    def printData(self):
        print('Product id:', self.product__id)
        print('Product name', self.product__name)

inventory = []

inventory.append(Product(1, 'Bacon'))
inventory.append(Product(2, 'Bread'))

num = 10
for item in inventory:
    item.printData()
    print('')
    item.changeDataProduct(num, f'Product{num}')
    print('')
    item.printData()
    print('')
    del item
    num += 10
