Working with multiple windows in tkinter

Thank you so much sir for this helpful video.❤🎉

Hi developers I need the Childfrom Frame with in window that execute multiple From windows appears

C# I used the code Childfrom that appear the panel

So Make vedio tkinter with Childfrom

Why not create one jupyter book for different action and call them in master file in form of menu

Is there a way to open a new window and close the old one?
Something for like a login screen.
When logged in successfully, the new window is created, and the first login screen is destroyed.
Would have to create a new `Tk()` somehow, idk with `Toplevel()` or just a regular old method.
Also how would I write the `.mainloop()`, if I'm using classes for all frames and components?

I need help!
My python program uses "import tkinter as tk" but doesn't use "from tkinter import ttk" and "from tkinter import messagebox"
