python-3.2 - 加重平均を見つけるのに助けが必要

Question

私のコードでエラーを取得する Traceback (最新の呼び出しは最後): File "C:/Users/Daniel Nase/Desktop/assignment 7 test.py", line 119, in main() File "C:/Users/Daniel Nase/ Desktop/assignment 7 test.py」、23 行目、メインの calculate_weighted_average(score_ammount,scores_t, score_weight, average1, num_t) ファイル「C:/Users/Daniel Nase/Desktop/assignment 7 test.py」、112 行目、calculate_weighted_average 内weighted_average_t = float(sum(average1))*float((score_weight.pop(0))/100) TypeError: /: 'str' および 'int' のオペランド型がサポートされていません

加重平均を計算しようとしていますが、何が間違っているのかわかりません...助けてください!!!!
