Python Functional Python The Lambda Lambada Partial

Don't know what this challenge is asking for.

Depending on what the challenge is actually wanting to see, this code works in the interpreter. What am I missing?

discounts.py
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)

discount_10 = list(map(partial(discount, amount=10), prices))
discount_25 = list(map(partial(discount, amount=25), prices))
discount_50 = list(map(partial(discount, amount=50), prices))
print(discount_10 + discount_25 + discount_50)
