Finally, we're ready to find our totals. Create a variable named total. Use map() to find the per-product totals for each item in prices, then use reduce (and add) to find the total value.
im not getting what im suppose to do for this task
from operator import add
from functools import reduce
prices = [
(6.99, 5),
(2.94, 15),
(156.99, 2),
(99.99, 4),
(1.82, 102)
]
def product_sales(x):
return x[0] * x[1]

- Create a variable named total.
- Use map() to find the per-product totals for each item in prices,
using the function from task 1
- then use reduce (and add) to find the total value.
the "map" expression will be the 2nd argument

But you're really close here, "map" already returns a list so you don't need the "list()" function.
