Find the position
Search a list and report where something is, counting from 0.
Loop over the positions with range(len(items)), so you have the index i as well as the item items[i]. return leaves the function straight away, which is exactly what you want at the first match. Return -1 only after the loop has checked every item.
Write find_index(items, target) that returns the position of the first target in items, or -1 if it is not there. Do not use .index().
