学生信息管理系统python初学者

以下是一个简单的学生信息管理系统的Python代码示例，适合初学者使用：

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

class StudentManagementSystem:
    def __init__(self):
        self.students = []

    def add_student(self, name, student_id, phone_number):
        # 检测学号是否重复/有误
        for student in self.students:
            if student.student_id == student_id:
                print("学号已存在，请重新输入！")
                return
        if not student_id.isdigit():
            print("学号必须为纯数字，请重新输入！")
            return

        # 检测手机号是否合法
        if not phone_number.isdigit() or len(phone_number) != 11:
            print("手机号格式不正确，请重新输入！")
            return

        student = Student(name, student_id, phone_number)
        self.students.append(student)
        print("学生信息添加成功！")

    def display_students(self):
        for student in self.students:
            print("姓名：", student.name)
            print("学号：", student.student_id)
            print("手机号：", student.phone_number)
            print()

# 创建学生管理系统对象
sms = StudentManagementSystem()

# 添加学生信息
sms.add_student("张三", "1001", "13812345678")
sms.add_student("李四", "1002", "13987654321")

# 显示学生信息
sms.display_students()
