Question

So previously in my class I had to write a python program where the user would enter the price for 5 different items, and it would calculate the subtotal, total tax owed and the total amount owed. Now I need to write a program that would do the same but would be done using modules in the code, I am having a hard time figuring modules out. Below is the code from the original program not using modules:

# Enter price for Item1
item1 = float(input('Enter the price for item1: '))

# Enter price for Item2
item2 = float(input('Enter the price for item2: '))

# Enter price for Item3
item3 = float(input('Enter the price for item3: '))

# Enter price for Item4
item4 = float(input('Enter the price for item4: '))

# Enter price for Item5
item5 = float(input('Enter the price for item5: '))

print()

# Calculate the total owed before tax
subTotal = item1 + item2 + item3 + item4 + item5
print('The subtotal of the items is: ', subTotal)

# Calculate the total tax amount owed
totalTax = subTotal * .06
print('The total tax owed is: ', totalTax)

# Calculate the total amount owed
totalAmount = subTotal + totalTax
print('The total amount owed is: ', totalAmount)

Answer 1

def getSum(item1, item2, item3, item4, item5):
    return item1 + item2 + item3 + item4 + item5

def getTotalTax(subtotal):
    return subTotal * .06

def getTotalAmount(subTotal, totalTax):
    return subTotal + totalTax

def main():
    # Enter price for Item1
    item1 = float(input('Enter the price for item1: '))

    # Enter price for Item2
    item2 = float(input('Enter the price for item2: '))

    # Enter price for Item3
    item3 = float(input('Enter the price for item3: '))

    # Enter price for Item4
    item4 = float(input('Enter the price for item4: '))

    # Enter price for Item5
    item5 = float(input('Enter the price for item5: '))

    print()

    # Calculate the total owed before tax
    subTotal = getSum(item1,item2,item3,item4,item5)
    print('The subtotal of the items is: ', subTotal)

    # Calculate the total tax amount owed
    totalTax = getTotalTax(subTotal)
    print('The total tax owed is: ', totalTax)

    # Calculate the total amount owed
    totalAmount = getTotalAmount(subTotal, totalTax)
    print('The total amount owed is: ', totalAmount)

main()
