是否继承父窗口并在tkinter中添加额外的按钮？

import tkinter as tk

class MyWindow(tk.Tk):
    def __init__(self):
        super().__init__()
        self.title("My Window")
        self.geometry("200x200")
        
        self.button1 = tk.Button(self, text="Button 1")
        self.button1.pack()
        
        self.button2 = tk.Button(self, text="Button 2")
        self.button2.pack()
        
        self.button3 = tk.Button(self, text="Button 3")
        self.button3.pack()
        
        self.button4 = tk.Button(self, text="Button 4")
        self.button4.pack()

if __name__ == "__main__":
    window = MyWindow()
    window.mainloop()
