A coffee chain has 3 shops and sells 5 drinks. Each shop has its own base price, and each drink adds its own extra on top. An analyst writes this code to build the price list and centre each shop's prices on that shop's own average:
In this chapter you've seen a flat strip of shape (3,) stretched onto every row of a (2, 3) grid, and an upright strip of shape (2, 1) stretched across every column of a (2, 3) grid. Here neither side is a full grid: base has shape (3, 1) and extra has shape (5,).
What happens when the code runs?
