Question

Create a program using Payton that determines the cost of 3 items shipped with tax.
The user will enter the following information for exactly 3 different items:

• Description
• Price
• Quantity
• Weight per item

You will capture the 4 pieces of information for each of the 3 items. You will then let the user know what they bought, how much is the SubTotal, Shipping & Handling costs, the Tax and the Total (format the output for these 4 totals as USD$ with two decimal places)

Answer 1

Problem by using an example

#code

#number of items
n=3
#list to store item names
items=[]
#to store sub total
sub_total=0
#to store shipping cost, $5 is fixed basic charge
shipping=5
#looping for n times
for i in range(n):
#prompting and reading all inputs
print('Item ',(i+1))
desc=input('Enter item description: ')
price=float(input('Enter item price: '))
quantity = int(input('Enter item quantity: '))
weight = float(input('Enter item weight (pounds): '))
#multiplying price and quantity, adding to sub total
sub_total+=price*quantity
#multiplying weight and quantity and 0.25, to get shipping cost, adding
#to shipping
shipping+=weight*0.25*quantity
#appending item name to items
items.append(desc)

#finding 9% of sub total as tax
tax=sub_total*0.09
#adding everything to get final total
total=sub_total+tax+shipping
#displaying everything in proper format.
#' '.join(items) will combine elements in a string list space separated
#{:.2f} will format a numeric value to 2 digits after decimal point
print("You have purchased: {}, The subtotal is ${:.2f}".format(' '.join(items),sub_total))
print("The Shipping and Handling costs are ${:.2f}".format(shipping))
print("The Tax is ${:.2f} The Total is ${:.2f}".format(tax,total))
