Please help, I don't know what to do.

The task is: We need to add two numbers together. We could write a function that does this but that seems silly.
Import add from the operator module.

Please give the code and explain how the code works.

Thank You! Jack

prices.py 
from operator import add


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]

It looks like you've already done it. The code shown here will pass task 2.

What kind of problem are you having?

Oh, I thought that you would have to do more than just import to complete the task, and didn't know if I should do anything next. After you told me that though, I copyed and pasted my code back in and it passed.

Thanks So Much!!!!!!! Jack

This one is simple, but it sets things up for task 3.
