Question

Module 6 - Cash Register (10 Points) We are going to write a program that simulates a customer's transaction at a cash register. You will organize your code using functions. Each of the functions below counts for 2 points. You must create functions allowing the user to: 1. Add an item to the order. No name or list of items is needed simply prompt the user for a dollar amount to add. 2. Clear all transactions. Set the amount of the order to $0.00. 3. Check out the order. It should involve taking a payment amount and calculating change. You receive 1 point for implementing error handling in a situation of your choice in this code. The remaining 1 point comes from completing the starter code for the user menu. This should utilize the functions you made. Hints: 1. You should define the order's total as a global variable. It should be a floating part number. Your functions should then use and/or modify this variable. 2. Do not overthink this assignment. Break the requirements down into functions and go from there. 3. The user menu code should simply call the functions you made, and not much more. Have the brunt of your work implemented in the function and not the if or elif statement. 4. Most students get points taken off for missing functionality. Do not forget all of the requirements. Missing requirements completely makes your assignment ineligible for a re-do.

Answer 1

Run code in python 3

And if you need any more info, comment me

import sys

order_total = 0.00


def add():
    """
    prompt the user to add amount
    :return:
    """
    add_amount = float(input("please add the amount to order: "))
    global order_total
    order_total += add_amount
    return add_amount


def clear():
    """
    clear total amount
    :return:
    """
    global order_total
    order_total = 0
    print(order_total)


def calcchange():
    """
    calculate change the amount
    :return:
    """
    global order_total
    cents = order_total*100+0.01
    dollars = int(cents /100)
    cents = cents %100
    quarters = int(cents/25)
    cents = cents %25
    dimes = int(cents/10)
    cents = cents %10
    nickels = int(cents/5)
    cents = cents %5
    pennies = int(cents)
    print("total Amaount", round(order_total, 2), "\n", dollars, "dollars", quarters,
          "quarters", dimes, "dimes", nickels, "nickels", pennies, "pennies")
    return order_total, dollars, quarters, dimes, nickels, pennies


isOrderDone = False
while (isOrderDone==False):
    print()
    userChoice = input("What would you like to do? "
                       "Enter A to add an item, C to clear this order, X to check out, or Q to quit.")
    # userChoice.upper() Accept lower case also 
    if (userChoice.upper() == "A"):
        add()
    elif (userChoice.upper() == "C"):
        clear()
    elif (userChoice.upper() == "X"):
        calcchange()
    elif (userChoice.upper() == "Q"):
        sys.exit(0)
    else:
        print("Invalid option entered, please try again")

the output is given below

What would you like to do? Enter A to add an item, C to clear this order, X to check out, or Q to quit.a
please add the amount to order: 45.36

What would you like to do? Enter A to add an item, C to clear this order, X to check out, or Q to quit.a
please add the amount to order: 78.42

What would you like to do? Enter A to add an item, C to clear this order, X to check out, or Q to quit.x

Total amount 123.78
 123 dollars 3 quarters 0 dimes 0 nickels 3 pennies

What would you like to do? Enter A to add an item, C to clear this order, X to check out, or Q to quit.c

What would you like to do? Enter A to add an item, C to clear this order, X to check out, or Q to quit.x
