Question

Calculate and display the retail price for product registration until user enter a negative wholesale cost.
Retail price = wholesale price * 0.25
Store all retail price list and print out a price list in table format.

What I have is below:

retail_price = 0
while (True):
wholesale_cost = int(input("Enter your wholesale cost:"))
if (wholesale_cost < 0):
break
else:
retail_price = wholesale_cost * 0.25
print(retail_price)

Answer 1

You just need to add a list variable, like prices = [] and append retail_price to it, each time it is calculated.
Then, when the loop is broken, print out this list.

Answer 2

it will be a very nice price list without products names))))
