python用面向对象写学生管理系统

好的，我可以为您提供一个简单的Python学生管理系统的面向对象代码示例:

class Student:
    def __init__(self, name, age, gender, grade):
        self.name = name
        self.age = age
        self.gender = gender
        self.grade = grade

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

    def add_student(self, student):
        self.student_list.append(student)

    def remove_student(self, student):
        self.student_list.remove(student)

    def get_student(self, name):
        for student in self.student_list:
            if student.name == name:
                return student
        return None

    def print_all_students(self):
        for student in self.student_list:
            print("Name: {}, Age: {}, Gender: {}, Grade: {}".format(student.name, student.age, student.gender, student.grade))

# 示例用法
sms = StudentManagementSystem()

# 添加学生
s1 = Student("Tom", 18, "male", "A")
sms.add_student(s1)

s2 = Student("Jane", 17, "female", "B")
sms.add_student(s2)

# 打印所有学生信息
sms.print_all_students()

# 查找学生
s3 = sms.get_student("Tom")
if s3:
    print("Found student: {}, Age: {}, Gender: {}, Grade: {}".format(s3.name, s3.age, s3.gender, s3.grade))
else:
    print("Student not found")

# 删除学生
sms.remove_student(s1)
sms.print_all_students()

这个学生管理系统包含两个类：一个是学生类，另一个是学生管理系统类。学生类用于存储学生信息，学生管理系统类用于添加、删除、查找和打印学生信息。这个系统可以通过实例化学生管理系统类，并通过调用其方法来进行操作。
