使用python设计一个简单的学生管理系统代码

好的，下面是一个简单的学生管理系统的Python代码示例：

class Student:
    def __init__(self, name, age, sex, id):
        self.name = name
        self.age = age
        self.sex = sex
        self.id = id

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

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

    def remove_student(self, id):
        for student in self.students:
            if student.id == id:
                self.students.remove(student)
                return True
        return False

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

    def show_all_students(self):
        for student in self.students:
            print("Name: {}, Age: {}, Sex: {}, ID: {}".format(student.name, student.age, student.sex, student.id))

if __name__ == '__main__':
    manager = StudentManager()
    student1 = Student("Tom", 18, "Male", "001")
    student2 = Student("Jerry", 19, "Female", "002")
    manager.add_student(student1)
    manager.add_student(student2)
    manager.show_all_students()

    manager.remove_student("001")
    manager.show_all_students()

    student = manager.search_student("002")
    if student:
        print("Name: {}, Age: {}, Sex: {}, ID: {}".format(student.name, student.age, student.sex, student.id))
    else:
        print("Student not found.")

以上代码实现了一个简单的学生管理系统，包含了添加学生、删除学生、查找学生、显示所有学生等功能。
