Question

Solve In Python

Please complete your own Snack Bar Menu program - Name your restaurant anything you like This program will display a menu of snacks and prices the user can choose from. After the user selects one the program will display a subtotal and then display the menu again. The user can select as many items as they choose until they choose to quit. Once the user chooses to quit the program will display the subtotal, the amount owed for tax, and a grand total. Then the program will offer a choice to order for an additional person and start all over if they say yes. Requirements: Get users name for order (store with cap letter) Must offer at least 5 menu items with prices, and have an exit option. Use numbers not string for the menu (1,2,3...) Must use Constants to store prices for each menu item. Use 7% tax Make sure to use a conditional loop to let the user keep ordering until they want to quit. Show them a new subtotal without tax after each menu item is added. When they choose to quit then show them the subtotal, amount of tax, and grand total. *HINT - You will need a decision structure for the running subtotal and errors. Make sure to show an error message if they choose a number not in the menu. At the end offer user a choice to order for an additional person and start all over if they say yes. *Make sure to include header comments and your entire algorithm as comments Please customize this program using your own title (designed), maybe some pauses, appropriate but fun output.... ***No while True loops - must use a condition!

Answer 1

To solve this problem in Python, you can use a combination of loops, conditional statements, and variables. The code provided allows the user to select items from a snack bar menu, calculate the subtotal, tax amount, and grand total, and offers the option to order for an additional person and start over. Constants are used to store the menu items and prices, and functions are defined to calculate the tax and grand total.

Step-by-step explanation:

To solve this problem in Python, you can use a combination of loops, conditional statements, and variables. Here's an example code that can be used to create a snack bar menu program:

import math

# Constants to store menu items and prices
ITEM_1 = 1
ITEM_2 = 2
ITEM_3 = 3
ITEM_4 = 4
ITEM_5 = 5
EXIT_OPTION = 6

# Prices for each menu item
PRICE_1 = 2.50
PRICE_2 = 1.75
PRICE_3 = 3.00
PRICE_4 = 2.25
PRICE_5 = 1.50

def calculate_tax(subtotal):
tax_rate = 0.07
tax_amount = subtotal * tax_rate
return tax_amount

def calculate_grand_total(subtotal, tax_amount):
grand_total = subtotal + tax_amount
return grand_total

def main():
# Get user's name
name = input('Enter your name: ').capitalize()

# Initialize variables
subtotal = 0
menu_choice = 0

# Display menu and get user's choice
while menu_choice != EXIT_OPTION:
print('Welcome to Snack Bar Menu!')
print('1. Item 1 ($', PRICE_1,')')
print('2. Item 2 ($', PRICE_2,')')
print('3. Item 3 ($', PRICE_3,')')
print('4. Item 4 ($', PRICE_4,')')
print('5. Item 5 ($', PRICE_5,')')
print('6. Exit')
menu_choice = int(input('Enter your choice: '))

# Calculate subtotal
if menu_choice == ITEM_1:
subtotal += PRICE_1
elif menu_choice == ITEM_2:
subtotal += PRICE_2
elif menu_choice == ITEM_3:
subtotal += PRICE_3
elif menu_choice == ITEM_4:
subtotal += PRICE_4
elif menu_choice == ITEM_5:
subtotal += PRICE_5
elif menu_choice == EXIT_OPTION:
break
else:
print('Invalid choice!')
continue

# Display new subtotal
print('New subtotal:', round(subtotal, 2))

# Calculate tax and grand total
tax_amount = calculate_tax(subtotal)
grand_total = calculate_grand_total(subtotal, tax_amount)

# Display final results
print('Subtotal:', round(subtotal, 2))
print('Tax amount:', round(tax_amount, 2))
print('Grand total:', round(grand_total, 2))

# Ask if user wants to order for an additional person and start over
choice = input('Do you want to order for an additional person? (yes or no): ')
if choice.lower() == 'yes':
main()

main()

In this program, the user's name is stored using the name variable. Constants are used to store the menu items and their respective prices. The program uses a loop to display the menu and get the user's choice. The subtotal is calculated based on the user's choice, and the new subtotal is displayed after each menu item is added. Finally, the tax amount and grand total are calculated and displayed, and the user is given the option to order for an additional person and start over.
