PYTHON学生成绩管理系统

python学生成绩管理系统，一个简单的示例：

class Student:
    def __init__(self, name, id):
        self.name = name
        self.id = id
        self.scores = []

    def add_score(self, score):
        self.scores.append(score)

    def average_score(self):
        return sum(self.scores) / len(self.scores)

class StudentManager:
    def __init__(self):
        self.students = {}

    def add_student(self, name, id):
        self.students[id] = Student(name, id)

    def add_score(self, id, score):
        if id in self.students:
            self.students[id].add_score(score)
        else:
            print("Student with ID {} not found.".format(id))

    def get_average_score(self, id):
        if id in self.students:
            return self.students[id].average_score()
        else:
            print("Student with ID {} not found.".format(id))

    def print_all_students(self):
        for id, student in self.students.items():
            print("ID: {}, Name: {}, Average Score: {}".format(id, student.name, student.average_score()))

# Example usage:
manager = StudentManager()

# Add students
manager.add_student("Alice", "1001")
manager.add_student("Bob", "1002")
manager.add_student("Charlie", "1003")

# Add scores
manager.add_score("1001", 90)
manager.add_score("1002", 80)
manager.add_score("1001", 95)
manager.add_score("1003", 85)

# Print average scores
print("Alice's average score:", manager.get_average_score("1001"))
print("Bob's average score:", manager.get_average_score("1002"))
print("Charlie's average score:", manager.get_average_score("1003"))

# Print all students
manager.print_all_students()

它的输出结果如下
