#this problem is about knowing how to iterate!!!!
nested for loop on this one gives me error - dont go one level deeper , it will start iterating over letters in each word!!
e.g. phone, blue, pixel:
    for i in item:
        i[0] - p
        i[1] - h
        i[2] - o
        instead of actual items! nested loop on item produces letters!!
