Hello everyone,
                         I am having problems getting my code to calculate sales discount.
I have modules that I imported; one of them is the sales price. I wonder if it has a direct effect on why the program is not calculating the sales discounts.
At the end of everything, it gives me $0.00, for the sub-total; $0.00 for the total discount, and $0.00 for the final price.

Please take a look at it for me.

The two imported modules are listed below, then the main Python code follows.
Thanks



# Project 4
# Chuka Ihemaguba
# The "RETAIL_PRICE" module

RETAIL_PRICE = 99



# Project 4
# Chuka Ihemaguba
# Welcome Shoppers

print("Welcome Shoppers!!!!!")
print("Below are the discounts on the product based on how many you buy.")
print("------------------------------------------------------------------\n")
print("Quantity of 100 or more items: 40% discount")
print("Quantity of 50-99 items: 30% discount")
print("Quantity of 20-49 items: 20% discount")
print("Quantity of 10-19 items: 10% discount")
print("Quantity of less than 10 items: No discount\n\n\n")
