有5个学生，每个学生的数据包括学号、姓名、3门课的成绩。从键盘输人5个学生数据，要求输出3门课总平均成绩，以及最高分的学生的数据(包括学号、姓名、3门课的成绩、平均分数。 要求：用三个函数实现

以下是实现你所需功能的Python代码：

def input_data():
    students = []
    for i in range(5):
        student = {}
        student['学号'] = input("请输入学号：")
        student['姓名'] = input("请输入姓名：")
        student['成绩1'] = float(input("请输入第一门课的成绩："))
        student['成绩2'] = float(input("请输入第二门课的成绩："))
        student['成绩3'] = float(input("请输入第三门课的成绩："))
        students.append(student)
    return students

def calculate_average(students):
    total_scores = [0, 0, 0]
    for student in students:
        total_scores[0] += student['成绩1']
        total_scores[1] += student['成绩2']
        total_scores[2] += student['成绩3']
    average_scores = [score/5 for score in total_scores]
    return average_scores

def find_highest_score(students):
    highest_score = 0
    highest_student = {}
    for student in students:
        average_score = (student['成绩1'] + student['成绩2'] + student['成绩3']) / 3
        if average_score > highest_score:
            highest_score = average_score
            highest_student = student
    return highest_student

students = input_data()
average_scores = calculate_average(students)
highest_student = find_highest_score(students)

print("3门课的总平均成绩为：", average_scores)
print("最高分的学生数据为：", highest_student)
