Question

I have a program I am trying to build as homework in PYTHON.

The program consists of a calculator for shopping where input asks the customer for the price of a product and then print;

1. The TOTAL of all products if the customer wishes to add it on

2. PRINTS "Do you wish to add this to your total"

then

3. The TOTAL.

then the program repeats as the customer continues to shop.

The program must also have a sentinel value to quit the program for the FINAL TOTAL.

So far, this is what I have come up with:

##
# Julian Bencomo
# Building a calculator

import math

# x = price of product
# y = Checking price before adding it to total
# z = TOTAL price * .0825 tax

x = float(int(input('Enter price of product: $ ')))
y = print('Your current total is: $ ', y)
z = ( 0 * 0.0825 ) + y

addToCart = input('Your total with this product becomes: $', x + y /n , 'Do you wish to add this to your cart? Enter Y for yes or N for no: ')

# STEP ONE
# Entering price
print(x)
if x > 0.001 :
print(y)

Answer 1

Python Code:

"""
   program consists of a calculator for shopping where input asks the customer for the price of a product and then print;
   1. The TOTAL of all products
"""

# Variable that holds total
total = 0

# Reading price of a product
price = float(input("Enter price of a product(-111 to stop): "))

# Loop
while price != -111:
   # Asking user
   op = input("Do you wish to add this to your total: (y/n): ")
  
   # If yes
   if op.lower() == 'y':
       # Adding total
       total += price
       # printing total
       print("\n Total :$%.2f \n"%(total))
          
   # Reading price of a product
   price = float(input("Enter price of a product(-111 to stop): "))      
  
  
# printing total
print("\n\n Final Total :$%.2f \n"%(total))
