[Tkinter] Command button, then more command buttons

[Yoriz]

Using Classes to make frames that contain buttons, destroying a frame will also destroy any child widgets of the frame.

import tkinter as tk


class Main:
    def __init__(self, root):
        self.root = root

        self.start_frame.pack()
