Please write a Python program to complete the following task:

Suppose a company offers quantity discounts. If up to $1,000$ units are purchased, the unit price is

$$10.$ If more than $1,000$ but up to $5,000$ units are purchased, the unit price is $$9.$ If more than $5,000$

units are purchased, the unit price is $$7\mathrm{.}50.$ Ask the user to enter the number of units they wish to

purchase, determine the unit price associated with the order quantity, and compute the total cost

of the order. Inform the user of the unit price and total cost of the order.
