Hi. I'm very very new to python. I have been working my way through a free python pdf file I found (python3handson.pdf) and I'm having trouble with one of my programs:

'''discount.py

Exercise 1.14.3.1. * Write a program, discount.py, that prompts the user for an original price and for a discount percentage and prints out the new price to the nearest cent. For example if the user enters 2.89 for the price and 20 for the discount percentage, the value would be (1- 20/100)*2.89, rounded to two decimal places, 2.31. For price .65 with a 25 percent discount, the value would be (1- 25/100)*.65, rounded to two decimal places, .49. 10 Write the general calculation code following the pattern of the calculations
illustrated in the two concrete examples.

'''

oPrice = 0
newPrice = 0
discount = 0

oPrice = input('What is the original price?  ')
discount = input('How much is this item discounted?  ')

oPrice = float(oPrice)
discount = float(discount)
newPrice = oPrice - (oPrice * discount)

print('The new price is {}' .format(newPrice, '.2f'))


When I run this thing, and I enter 5.00 for original price and .2 for the discount, it always results in 4.0. When I entered my format function call directly into the shell, it comes out like I would expect:



>>> format(4.0, '.2f')
'4.00'


What exactly am I doing wrong here?
