从键盘输入3个学生数据，要求输出3门课程总平均成绩，以及最高分的学生数据（包括学号、姓名、3门课程平均成绩、平均分数）

可以回答这个问题。以下是代码示例：

请依次输入3个学生的学号、姓名、3门课程成绩（用空格分隔）：

student1 = input().split()
student2 = input().split()
student3 = input().split()

计算3门课程总平均成绩：

avg_score1 = (int(student1[2]) + int(student2[2]) + int(student3[2])) / 3
avg_score2 = (int(student1[3]) + int(student2[3]) + int(student3[3])) / 3
avg_score3 = (int(student1[4]) + int(student2[4]) + int(student3[4])) / 3

找出最高分的学生数据：

max_score = max(int(student1[2]), int(student1[3]), int(student1[4]), int(student2[2]), int(student2[3]), int(student2[4]), int(student3[2]), int(student3[3]), int(student3[4]))

if max_score == int(student1[2]):
    max_student = student1
elif max_score == int(student1[3]):
    max_student = student1
elif max_score == int(student1[4]):
    max_student = student1
elif max_score == int(student2[2]):
    max_student = student2
elif max_score == int(student2[3]):
    max_student = student2
elif max_score == int(student2[4]):
    max_student = student2
elif max_score == int(student3[2]):
    max_student = student3
elif max_score == int(student3[3]):
    max_student = student3
else:
    max_student = student3

输出结果：

print("3门课程总平均成绩为：", (avg_score1 + avg_score2 + avg_score3) / 3)
print("最高分的学生数据为：学号：", max_student[0], "姓名：", max_student[1], "3门课程平均成绩：", (int(max_student[2]) + int(max_student[3]) + int(max_student[4])) / 3, "平均分数：", max_score)
