dont know what to do
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 * x

Try breaking down the instructions into steps:
- 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
