Need Help with Python 3 Coding for the following:

A consignment shop accepts a product for sale and sets an initial price. Each month that the item doesnt sell, the price is reduced by 10 percent. When the item sells, the items owner receives 70 percent of the sale price, and the shop gets 30 percent. Write a program to represent the logic of a program that allows the user to enter an original product price. The output is the sale price, the owners cut, and the shops cut each month for the first three months the item is on sale.
