输入三门课成绩编写函数计算三门课程总分和平均值。用例：输入：959878输出：成绩总和： 271平均成绩： 903

def calculate_score(score1, score2, score3): total_score = score1 + score2 + score3 average_score = total_score / 3 print("成绩总和：", total_score) print("平均成绩：", round(average_score, 1))

score1 = int(input()) score2 = int(input()) score3 = int(input())

calculate_score(score1, score2, score3)
