Python How to clear window in tkinter

Question

I need to clear window before I load a new map. But menu buttons have to stay. I was trying self.frame.destroy(), but it kill my menu buttons too. Basically I need to clear class Sokoban, but this class is not in class Window. Problem is in def map1(self): and def map2(self):

import tkinter
from tkinter import *

class Window(Frame):

    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.master = master
        self.init_window()

    def init_window(self):
        self.master.title('Sokoban')
        self.pack(fill = BOTH, expand = 1)
        menu = Menu(self.master)
        self.master.config(menu=menu)

        file = Menu(menu)
        file.add_command(label='Mapa1', command = self.map1)
        menu.add_cascade(label='Mapy', menu=file)

        edit = Menu(menu)
        edit.add_command(label='Mapa2', command = self.map2)
        menu.add_cascade(label='Edit', menu=edit)

    def map1(self):
        self.frame.forget()
        Sokoban('map1.txt')

    def map2(self):
        self.frame.forget()
        Sokoban('map2.txt')

That not-working wall of code is very hard to work with so I will try to answer your menu buttons have to stay part with an example code. Basically you create two frames, one holds widgets going to be cleared and second one holds other widgets plus first frame.

import tkinter as tk

root = tk.Tk()
root.geometry("300x300")

frame1 = tk.Frame(root)
frame2 = tk.Frame(frame1)
frame1.pack()
frame2.pack()
menubar = tk.Menu(frame1) 
menubar.add_command(label="Bring Back!", command=frame2.pack)
menubar.add_command(label="Quit!", command=root.destroy)

tk.Button(frame2, text="Forget only frame2", command=frame2.pack_forget).pack()
tk.Label(frame2, text="Label on frame2").pack()

root.config(menu=menubar)

root.mainloop()
