# Task 1 of 4
# First, import 'partial' from 'functools'.
from functools import partial
prices = [ 10.50, 9.99, 0.25, 1.50, 8.79, 101.25, 8.00]
def discount(price, amount):
return price - price * (amount/100)
# A 'partial' is a function where some of its input parameters have
# already been defined.
# The function 'discount' has two parameters: 'price' and 'amount'.
# The new function 'discount_10' has one parameter: 'price'.
# The amount is pre-defined using the 'partial' command
# Task 2 of 4
# Now, use 'partial' to make a version of 'discount' that applies
# a 10% discount. Name this partial function 'discount_10'.
discount_10 = partial(discount, amount=10)
Now, discount_10(15.00)
is equivalent to discount(15.00, 10)
Task 3 is an trivial extension to Task2. Task 4 uses map
in a straight-forward manner.
