我对Tkinter非常陌生并且必须将它用于我的编程课程，我正在寻找帮助以了解如何在打开SuccessfulLogin窗口时销毁/隐藏LoginWindow。请记住，我是tkinter的新手。谢谢。

基于this answer可以生成以下示例。

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()

首先在示例窗口中显示aWindow，当您单击其上的按钮时，它会销毁aWindow并再次显示root窗口。
