You almost have it. But .index is a method used for finding an index for certain contents, you won't need that here.

:point_right: You just need to get the first letter of the item (index of 0), using the indexing operator: [] (brackets).

        if item[0] == "a":

You need to change your for statement so it loops until it gets to last item. You need a function that determines how many items are in array then make it part of for statement.

Actually, he for...in statement he has already handles that nicely, without needing to keep track of the count of items.
