Menu dictionary

menu = { "Snacks": { "Cookie": .99, "Banana": .69, "Apple": .49, "Granola bar": 1.99 }, "Meals": { "Burrito": 4.49, "Teriyaki Chicken": 9.99, "Sushi": 7.49, "Pad Thai": 6.99, "Pizza": { "Cheese": 8.99, "Pepperoni": 10.99, "Vegetarian": 9.99 }, "Burger": { "Chicken": 7.49, "Beef": 8.49 } }, "Drinks": { "Soda": { "Small": 1.99, "Medium": 2.49, "Large": 2.99 }, "Tea": { "Green": 2.49, "Thai iced": 3.99, "Irish breakfast": 2.49 }, "Coffee": { "Espresso": 2.99, "Flat white": 2.99, "Iced": 3.49 } }, "Dessert": { "Chocolate lava cake": 10.99, "Cheesecake": { "New York": 4.99, "Strawberry": 6.49 }, "Australian Pavlova": 9.99, "Rice pudding": 4.99, "Fried banana": 4.49 } }

1. Set up order list. Order list will store a list of dictionaries for

menu item name, item price, and quantity ordered

order = []

Launch the store and present a greeting to the customer

print("Welcome to the variety food truck.")

Customers may want to order multiple items, so let's create a continuous

loop

place_order = True while place_order: # Ask the customer from which menu category they want to order print("From which menu would you like to order? ")

# Create a variable for the menu item number
i = 1
# Create a dictionary to store the menu for later retrieval
menu_items = {}

# Print the options to choose from menu headings (all the first level
# dictionary items in menu).
for key in menu.keys():
    print(f"{i}: {key}")
    # Store the menu category associated with its menu item number
    menu_items[i] = key
    # Add 1 to the menu item number
    i += 1

# Get the customer's input
menu_category = input("Type menu number: ")

# Check if the customer's input is a number
if menu_category.isdigit():
    # Check if the customer's input is a valid option
    if int(menu_category) in menu_items.keys():
        # Save the menu category name to a variable
        menu_category_name = menu_items[int(menu_category)]
        # Print out the menu category name they selected
        print(f"You selected {menu_category_name}")

        # Print out the menu options from the menu_category_name
        print(f"What {menu_category_name} item would you like to order?")
        i = 1
        menu_items = {}
        print("Item # | Item name                | Price")
        print("-------|--------------------------|-------")
        for key, value in menu[menu_category_name].items():
            # Check if the menu item is a dictionary to handle differently
            if type(value) is dict:
                for key2, value2 in value.items():
                    num_item_spaces = 24 - len(key + key2) - 3
                    item_spaces = " " * num_item_spaces
                    print(f"{i}      | {key} - {key2}{item_spaces} | ${value2}")
                    menu_items[i] = {
                        "Item name": key + " - " + key2,
                        "Price": value2
                    }
                    i += 1
            else:
                num_item_spaces = 24 - len(key)
                item_spaces = " " * num_item_spaces
                print(f"{i}      | {key}{item_spaces} | ${value}")
                menu_items[i] = {
                    "Item name": key,
                    "Price": value
                }
                i += 1

        # 2. Ask customer to input menu item number
        menu_selection = input("Type item number: ")

        # 3. Check if the customer typed a number
        if menu_selection.isdigit():
            # Convert the menu selection to an integer
            menu_selection = int(menu_selection)

            # 4. Check if the menu selection is in the menu items
            if menu_selection in menu_items:
                # Store the item name as a variable
                item_name = menu_items[menu_selection]["Item name"]
                item_price = menu_items[menu_selection]["Price"]

                # Ask the customer for the quantity of the menu item
                quantity = input(f"How many {item_name}(s) would you like to order? ")

                # Check if the quantity is a number, default to 1 if not
                if not quantity.isdigit():
                    print("Invalid input. Quantity will default to 1.")
                    quantity = 1
                else:
                    quantity = int(quantity)

                # Add the item name, price, and quantity to the order list
                order.append({"Item name": item_name, "Price": item_price, "Quantity": quantity})
            else:
                # Tell the customer that their input isn't valid
                print(f"{menu_selection} is not a valid menu option.")
        else:
            # Tell the customer they didn't select a menu option
            print(f"{menu_category} was not a menu option.")
    else:
        # Tell the customer they didn't select a menu option
        print(f"{menu_category} was not a menu option.")
else:
    # Tell the customer they didn't select a number
    print("You didn't select a number.")

while True:
    # Ask the customer if they would like to order anything else
    keep_ordering = input("Would you like to keep ordering? (Y)es or (N)o ")

    # 5. Check the customer's input
    if keep_ordering.lower() == 'y':
        # Keep ordering
        place_order = True
        # Exit the keep ordering question loop
        break
    elif keep_ordering.lower() == 'n':
        # Since the customer decided to stop ordering, thank them for
        # their order
        print("Thank you for your order")
        # Complete the order
        place_order = False
        # Exit the keep ordering question loop
        break
    else:
        # Tell the customer to try again
        print("Invalid input. Please type 'y' or 'n'.")

Print out the customer's order

print("This is what we are preparing for you.\n")

print("Item name | Price | Quantity") print("--------------------------|--------|----------")

6. Loop through the items in the customer's order

for item in order: # 7. Store the dictionary items as variables item_name = item["Item name"] item_price = item["Price"] item_quantity = item["Quantity"]

# 8. Calculate the number of spaces for formatted printing
num_item_spaces = 24 - len(item_name)
item_spaces = " " * num_item_spaces

# 9. Create space strings
price_spaces = " " * (6 - len(f"{item_price:.2f}"))
quantity_spaces = " " * (8 - len(str(item_quantity)))

# 10. Print the item name, price, and quantity
print(f"{item_name}{item_spaces} | ${item_price:.2f}{price_spaces} | {item_quantity}{quantity_spaces}")

11. Calculate the cost of the order using list comprehension

Multiply the price by quantity for each item in the order list, then sum()

and print the prices.

total_price = sum(item["Price"] * item["Quantity"] for item in order) print(f"\nTotal cost: ${total_price:.2f}")
