Tkinter - Tkinterの別のウィンドウを開いている間にウィンドウを閉じる方法 - Python 3

Question

私はTkinterには非常に慣れているので、プログラミングの授業でこれを使用しなければなりません。 SuccessfulLoginウィンドウが開きます。私はtkinterに新しいことを覚えておいてください。ありがとうございました。

from tkinter import ttk

this answerに基づいて、以下の実施例を作製することができる。例では

import tkinter as tk 

root = tk.Tk() 

#In order to hide main window 
root.withdraw() 

tk.Label(root, text="This is the main window").pack() 

aWindow = tk.Toplevel(root) 

def change_window(): 
    #remove the other window entirely 
    aWindow.destroy() 

    #make root visible again 
    root.iconify() 
    root.deiconify() 

tk.Button(aWindow, text="This is aWindow", command=change_window).pack() 

root.mainloop() 

は、最初のウィンドウ aWindowがあります、そしてあなたはそれの上のボタンをクリックしたとき、それは aWindowを破壊し、再び rootウィンドウが表示されるようになります。
