ANNACHI KADAI – The Dictionary

3 August 2024 at 09:23

In a vibrant town in Tamil Nadu, there is a popular grocery store called Annachi Kadai. This store is always bustling with fresh deliveries of items.

The store owner, Pandian, uses a special inventory system to track the products. This system functions like a dictionary in Python, where each item is labeled with its name, and the quantity available is recorded.

Morning: Delivering Items to the Store

One bright morning, a new delivery truck arrives at the grocery store, packed with fresh items. Pandian records these new items in his inventory list.

Creating and Updating the Inventory:


# Initial delivery of items to the store
inventory = {
    "apples": 20,
    "bananas": 30,
    "carrots": 15,
    "milk": 10
}

print("Initial Inventory:", inventory)
# Output: Initial Inventory: {'apples': 20, 'bananas': 30, 'carrots': 15, 'milk': 10}

Noon: Additional Deliveries

As the day progresses, more deliveries arrive with additional items that need to be added to the inventory. Pandian updates the system with these new arrivals.

Adding New Items to the Inventory:


# Adding more items from the delivery
inventory["bread"] = 25
inventory["eggs"] = 50

print("Updated Inventory:", inventory)
# Output: Updated Inventory: {'apples': 20, 'bananas': 30, 'carrots': 15, 'milk': 10, 'bread': 25, 'eggs': 50}

Afternoon: Stocking the Shelves

In the afternoon, Pandian notices that some items are running low and restocks them by updating the quantities in the inventory system.

Updating Quantities:


# Updating item quantities after restocking shelves
inventory["apples"] += 10  # 10 more apples added
inventory["milk"] += 5     # 5 more bottles of milk added

print("Inventory after Restocking:", inventory)
# Output: Inventory after Restocking: {'apples': 30, 'bananas': 30, 'carrots': 15, 'milk': 15, 'bread': 25, 'eggs': 50}

Evening: Removing Sold-Out Items

As evening falls, some items are sold out, and Pandian needs to remove them from the inventory to reflect their unavailability.

Removing Items from the Inventory:


# Removing sold-out items
del inventory["carrots"]

print("Inventory after Removal:", inventory)
# Output: Inventory after Removal: {'apples': 30, 'bananas': 30, 'milk': 15, 'bread': 25, 'eggs': 50}

Night: Checking Inventory

Before closing the store, Pandian checks the inventory to ensure that all items are accurately recorded and none are missing.

Checking for Items:

# Checking if specific items are in the inventory
is_bananas_in_stock = "bananas" in inventory
is_oranges_in_stock = "oranges" in inventory

print(f"Are bananas in stock? {is_bananas_in_stock}")
print(f"Are oranges in stock? {is_oranges_in_stock}")
# Output: Are bananas in stock? True
# Output: Are oranges in stock? False

Midnight: Reviewing Inventory

After a busy day, Pandian reviews the entire inventory to ensure all deliveries and sales are accurately recorded.

Iterating Over the Inventory:


# Reviewing the final inventory
for item, quantity in inventory.items():
    print(f"Item: {item}, Quantity: {quantity}")

# Output:
# Item: apples, Quantity: 30
# Item: bananas, Quantity: 30
# Item: milk, Quantity: 15
# Item: bread, Quantity: 25
# Item: eggs, Quantity: 50
