Don't understand why this is not letting me pass. My code works... It meets all the requirements stated in the objective... total = reduce(add,list(map(product_sales, prices)))

prices = [
    (6.99, 5),
    (2.94, 15),
    (156.99, 2),
    (99.99, 4),
    (1.82, 102)

def product_sales(price_unit):
    price, unit = price_unit
    return price * unit

from operator import add

from functools import reduce

total = reduce(add,list(map(product_sales, prices)))

It's not necessary to convert the "map" output to a list, and apparently that's confusing the validator.

But since this shouldn't hurt anything in actual practice, you might want to report it as a bug to the Support folks.
