Object Oriented Coffee Maker Machine : Python

 

Object Oriented Coffee 

Maker Machine

( Python Based ) 

The functionality given to the virtual coffee machine is a replica of our actual coffee machine. But, this oops-oriented coffee machine can only take order one out of latte/espresso/cappuccino.

The code is designed after determining 5 conditions to serve the coffee:

• Turn On & Off the machine
• Print the available quantity of the resources & money
• Process the made payment by the user
• Here, check out the given payment is ok?
• Serve the coffee

Before solving the above-mentioned conditions, the modules containing these functionalities are imported. And the functionality of these modules can be understood from below given class's documentation:

MenuItem Class

Attributes:

        

• name

(str) The name of the drink.

e.g. “latte”

• cost

(float) The price of the drink.

e.g 1.5

• ingredients

(dictionary) The ingredients and amounts required to make the drink.

e.g. {“water”: 100, “coffee”: 16}

Menu Class

Methods:

• get_items()

Returns all the names of the available menu items as a concatenated string.

e.g. “latte/espresso/cappuccino”

• find_drink(order_name)

Parameter order_name: (str) The name of the drinks order.

Searches the menu for a particular drink by name. Returns a MenuItem object if it exists, otherwise returns None.

CoffeeMaker Class

Methods:

• report()

Prints a report of all resources.

e.g.

Water: 300ml

Milk: 200ml

Coffee: 100g

• is_resource_sufficient(drink)

Parameter drink: (MenuItem) The MenuItem object to make.

Returns True when the drink order can be made, False if ingredients are insufficient.

e.g.

True

• make_coffee(order)

Parameter order: (MenuItem) The MenuItem object to make.

Deducts the required ingredients from the resources.

MoneyMachine Class

Methods:

• report()

Prints the current profit

e.g.

Money: $0

• make_payment(cost)

Parameter cost: (float) The cost of the drink.

Returns True when payment is accepted, or False if insufficient.

e.g. False

Final Code Structure

1. Turn On & Off the machine

is_on=True

while is_on:

options = menu.get_items()
choice = input(f"What would you like? ({options}):").lower()
 
    if choice =='off':
        is_on = False

2. Print the available quantity of the resources & money - The final report

from menu import Menu, MenuItem
from coffee_maker import CoffeeMaker
from money_machine import MoneyMachine


coffee = CoffeeMaker()
money = MoneyMachine()
menu = Menu()

is_on = True

while is_on:
    options = menu.get_items()
    choice = input(f"What would you like? ({options}):").lower()

    if choice =='off':
        is_on = False
    elif choice == 'report':
        money.report()
        coffee.report()
3. & 4. Process the made payment by the user. Also, check out the given payment is ok?

from menu import Menu, MenuItem
from coffee_maker import CoffeeMaker
from money_machine import MoneyMachine


coffee = CoffeeMaker()
money = MoneyMachine()
# menuitem = MenuItem()
menu = Menu()
is_on=True

while is_on:
    options = menu.get_items()
    choice = input(f"What would you like? ({options}):").lower()

    if choice =='off':
        is_on = False
    elif choice == 'report':
        money.report()
        coffee.report()
    else:
        drink = menu.find_drink(choice)
        if coffee.is_resource_sufficient(drink):
            if money.make_payment(drink.cost):

5. Serve the coffee

from menu import Menu, MenuItem
from coffee_maker import CoffeeMaker
from money_machine import MoneyMachine


coffee = CoffeeMaker()
money = MoneyMachine()
menu = Menu()

is_on = True

while is_on:
    options = menu.get_items()
    choice = input(f"What would you like? ({options}):").lower()

    if choice =='off':
        is_on = False
    elif choice == 'report':
        money.report()
        coffee.report()
    else:
        drink = menu.find_drink(choice)
        if coffee.is_resource_sufficient(drink):
            if money.make_payment(drink.cost):
                coffee.make_coffee(drink)
