Move an item between two carts in place

A shop lets customers move an item from their cart to their wish list. The page holds references to both lists, so the function must change those lists in place, not build new ones. And when both arguments are the very same list, there is nothing to move.

Functionmove_item(source, target, sku)

Effectremove the first sku from source and append it to target, changing both lists in place

ReturnsTrue if the item was moved; False (and nothing changes) when sku isn't in source or when source and target are the same list object

Examples

callmove_item(['SPO-11681', 'HOM-22847'], ['ELE-24781'], 'HOM-22847')returnsTrue

callmove_item(['SPO-11681'], [], 'BOO-58412')returnsFalse

callmove_item(['A', 'B'], ['C'], 'A')returnsTrue
