请制作一个thinker 界面学生管理系统 Python

好的，以下是一个简单的思考者界面学生管理系统Python代码示例：

import tkinter as tk

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

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

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

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

    def get_student_by_name(self, name):
        for student in self.students:
            if student.name == name:
                return student

    def get_all_students(self):
        return self.students

class App:
    def __init__(self):
        self.window = tk.Tk()
        self.window.title("学生管理系统")
        self.system = StudentManagementSystem()

        self.name_label = tk.Label(self.window, text="姓名：")
        self.name_label.pack()
        self.name_entry = tk.Entry(self.window)
        self.name_entry.pack()

        self.grade_label = tk.Label(self.window, text="年级：")
        self.grade_label.pack()
        self.grade_entry = tk.Entry(self.window)
        self.grade_entry.pack()

        self.add_button = tk.Button(self.window, text="添加学生", command=self.add_student)
        self.add_button.pack()

        self.remove_button = tk.Button(self.window, text="删除学生", command=self.remove_student)
        self.remove_button.pack()

        self.search_button = tk.Button(self.window, text="搜索学生", command=self.search_student)
        self.search_button.pack()

        self.show_all_button = tk.Button(self.window, text="显示所有学生", command=self.show_all_students)
        self.show_all_button.pack()

        self.result_label = tk.Label(self.window, text="")
        self.result_label.pack()

    def add_student(self):
        name = self.name_entry.get()
        grade = self.grade_entry.get()
        self.system.add_student(name, grade)

    def remove_student(self):
        name = self.name_entry.get()
        student = self.system.get_student_by_name(name)
        if student:
            self.system.remove_student(student)

    def search_student(self):
        name = self.name_entry.get()
        student = self.system.get_student_by_name(name)
        if student:
            self.result_label.config(text="姓名：{} 年级：{}".format(student.name, student.grade))
        else:
            self.result_label.config(text="没有找到该学生")

    def show_all_students(self):
        students = self.system.get_all_students()
        if students:
            result = ""
            for student in students:
                result += "姓名：{} 年级：{}\n".format(student.name, student.grade)
            self.result_label.config(text=result)
        else:
            self.result_label.config(text="没有学生")

    def run(self):
        self.window.mainloop()

if __name__ == "__main__":
    app = App()
    app.run()

这个简单的学生管理系统使用了Tkinter库创建了一个简单的GUI界面，可以添加、删除、搜索和显示所有学生。
