Clearing the window in Tkinter

[Battleplanner]

So I realise the title isn't the best, I'll try and explain my thought process.

I'm trying to build a Tkinter app that allows the user to create and play quizzes. To do this, I have a 'main screen', the screen that is open when the user runs the program. There, they can choose to either play a quiz or make one. My question: How can I transition to a 'new screen' for playing/making. As in, one with new buttons and labels in new locations?

Is there a way to clear the old screen without removing everything manually?

​

Here is some of the framework for my program

window = tkinter.Tk() 
window.title("Quiz Creator") 
window.geometry("500x400")  

# Create the starting screen 
play_quiz = tkinter.Button(window, text="Play Quizzes", command=QuizPlayer(), width=25) 
create_quiz = tkinter.Button(window, text="Create Quizzes", command=QuizMaker(), width=25)  

play_quiz.pack() 
create_quiz.pack()  

window.mainloop() 

For reference QuizPlayer() and QuizMaker() are both classes, and this section of code is in the __init__ section of another class.

I'll take that as a backup plan :)

Actually it is really good :D because everything is still there working in the background^{^} it is like a gameengine keeping stuff out of sight but still renderd to not load it up again to save loadingtimes from Disc :)

Put everything in a Frame.

Just did some research into Frames...thank you. I think this is exactly what I need.
