Where is it?

Write index_of(items, target) returning the position of the first target in the list, or -1 if it is not there — without .index().

def index_of(items, target):
    for i in range(len(items)):
        if items[i] == target:
            return i
        else:
            return -1

Run adds print(index_of([4, 8, 15], 8)) after your code, to try it.

Stuck on the idea rather than the code? The Searching lesson walks through it.
