利用类和对象进行成绩处理

以下是一个简单的成绩处理程序：

class Student:
    def __init__(self, name, score):
        self.name = name
        self.score = score

    def print_info(self):
        print(f"Name: {self.name}, Score: {self.score}")

class ScoreProcessor:
    def __init__(self, students):
        self.students = students

    def get_total_score(self):
        total_score = 0
        for student in self.students:
            total_score += student.score
        return total_score

    def get_average_score(self):
        total_score = self.get_total_score()
        return total_score / len(self.students)

    def get_highest_score(self):
        highest_score = 0
        for student in self.students:
            if student.score > highest_score:
                highest_score = student.score
        return highest_score

    def get_lowest_score(self):
        lowest_score = 100
        for student in self.students:
            if student.score < lowest_score:
                lowest_score = student.score
        return lowest_score

if __name__ == "__main__":
    students = [
        Student("Tom", 80),
        Student("Jerry", 90),
        Student("Alice", 70),
        Student("Bob", 85)
    ]

    processor = ScoreProcessor(students)

    print(f"Total score: {processor.get_total_score()}")
    print(f"Average score: {processor.get_average_score()}")
    print(f"Highest score: {processor.get_highest_score()}")
    print(f"Lowest score: {processor.get_lowest_score()}")

    for student in students:
        student.print_info()

输出结果：

Total score: 325
Average score: 81.25
Highest score: 90
Lowest score: 70
Name: Tom, Score: 80
Name: Jerry, Score: 90
Name: Alice, Score: 70
Name: Bob, Score: 85
