Annachi Kadai

In Tamil Nadu there was shop called Annachi Kadai. The owner of the shop is Pandiyan. Now we learn Python using this case study.

Morning:

In the early morning the goods for shop will come. Then Pandiyan will take a note on the goods.

One day the goods came to his shop and he take a note on it. They are:-

inventory = { "apples": 20, "bananas": 30, "carrots": 15, "milk": 10 }
Enter fullscreen mode Exit fullscreen mode

He want to check the list.

print(inventory) { 'apples': 20, 'bananas': 30, 'carrots': 15, 'milk': 10 }
Enter fullscreen mode Exit fullscreen mode

Noon:

As the time going the delivery also increases. So he add more inventories.

inventory["bread"] = 25 inventory["eggs"] = 50
Enter fullscreen mode Exit fullscreen mode

Then he want to check the list

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

Afternoon:

Then in the afternoon the quantities of the goods is going less. So he buyed some goods and he want that to add it on the list.

inventory["apples"] += 10 inventory["milk"] += 5
Enter fullscreen mode Exit fullscreen mode

Then he want to check the list

print("Inventory after Restocking:", inventory) Inventory after Restocking: {'apples': 30, 'bananas': 30, 'carrots': 15, 'milk': 15, 'bread': 25, 'eggs': 50}
Enter fullscreen mode Exit fullscreen mode

Evening:

In evening many of goods have sold. So he want to remove it from the list.

del inventory["carrots"]
Enter fullscreen mode Exit fullscreen mode

then he want to check the list.

print("Inventory after Removal:", inventory) Inventory after Removal: {'apples': 30, 'bananas': 30, 'milk': 15, 'bread': 25, 'eggs': 50}
Enter fullscreen mode Exit fullscreen mode

Night:

Before closing the shop. He wants to check the inventory is the inventories are correct.

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}") Are bananas in stock? True Are oranges in stock? False
Enter fullscreen mode Exit fullscreen mode

This things only we learnt in the python class.
