在Python3中如何关闭一个窗口同时打开另一个窗口

我对Tkinter非常陌生，必须将其用于我的编程课程，我正在寻找帮助，以了解如何在SuccessfulLogin窗口打开时销毁/隐藏登录窗口。记住我是新手。谢谢您。在

y = (screen_height / 2) - (height / 2)
root.geometry('%dx%d+%d+%d' % (width, height, x, y))


root = tkinter.Tk()
centerWindow(310, 375)
root.resizable(False,False)
loginWindow(root)
root.mainloop(

基于this answer可以生成下面的示例。在

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()

在第一个示例中，有一个窗口aWindow，当您单击它上的按钮时，它会破坏aWindow，并使root窗口再次可见。在
