8,515 PointsUnhelpful error feedback
Challenge Task 1 of 4 says "Let's start by writing a function named product_sales that takes a single two-member tuple made up of a price and a number of units sold. product_sales should return the product of the price and the number of units." - I don't know if I have the answer or not but neither the video, or the error feedback is being helpful. I don't understand where the error "Bummer! product_sales threw an exception when given the argument (10.5, 2)"
prices = [
(6.99, 5),
(2.94, 15),
(156.99, 2),
(99.99, 4),
(1.82, 102)
]
def product_sales(x, y):
return x * y

So here's some hints:
- the challenge says the function should take a single argument (yours currently takes two).
- the argument will be a two-member tuple, so you will subscript it to get the 2 values
- subscripting is done with brackets ("
[]") - the indexes of tuple members starts with 0

8,515 PointsThank you!
Where does it get the argument (10.5, 2)? Is that a built in test happening behind the scenes?
