The program in Python is as follows:
qty = int(input("Quantity: "))
price = 100 * qty
if qty >1000:
price = (100 - 0.10 * 100) * qty

qty = int(input("Quantity: "))
This calculates the price or cost, without discount
price = 100 * qty
This checks if the quantity is greater than 1000
if qty >1000:

price = (100 - 0.10 * 100) * qty
This prints the calculated cost
print("Cost: "+str(price))
