Oops, try again. Make sure to print the result of the grades_sum() function.
...errr, wat? I did print the result and I have done everything right, I know I'm very close there is just one small thing missing that I'm doing wrong. Just tell me and explain it to me because I have spent two hours here and I cannot figure it out. THANNNNNNKS
grades = [100, 100, 90, 40, 80, 100, 85, 70, 90, 65, 90, 85, 50.5] def grades_sum(scores): total = 0 for item in scores: total += item return total print grades_sum(scores)
