写基于python的学生管理系统设计开发的代码

好的，以下是一个简单的学生管理系统的Python代码：

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

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

    def add_student(self, name, id_number, major):
        student = Student(name, id_number, major)
        self.students.append(student)

    def remove_student(self, id_number):
        for student in self.students:
            if student.id_number == id_number:
                self.students.remove(student)

    def search_student(self, id_number):
        for student in self.students:
            if student.id_number == id_number:
                return student
        return None

    def display_students(self):
        for student in self.students:
            print("Name: {}, ID Number: {}, Major: {}".format(student.name, student.id_number, student.major))

# Example usage
sms = StudentManagementSystem()

sms.add_student("John Smith", "1234", "Computer Science")
sms.add_student("Jane Doe", "5678", "Mathematics")

sms.display_students()

sms.remove_student("5678")

sms.display_students()

student = sms.search_student("1234")
if student:
    print("Found student: Name: {}, ID Number: {}, Major: {}".format(student.name, student.id_number, student.major))
else:
    print("Student not found.")

这是一个简单的面向对象的设计，包含学生类和学生管理系统类。学生管理系统类包含添加学生、删除学生、搜索学生和显示学生列表等功能。你可以根据需求扩展这个代码。
