python - How to make a frame browser in tkinter?

Question

I am new to using tkinter in python and I was wondering how to make a window that has two buttons (one on the front and one on the back), with which a number of frames can be displayed one at a time and, once they have all crossed, they return to start indefinitely, pressing any of the two buttons (one would repeat this action from start to finish and the other from end to start)

this is my code sketch:

from tkinter import *
x = 0
mas = 1
menos = 0
c = []
def f(v):
    if v == 1:
        
        c.append(x)
        #print(len(c))
    elif v == 0:
        c.remove(c[len(c)-1])
        #print(len(c))
    
    j = len(c) -1
    

    print(j)

    lst[j-1].pack_forget()
    lst[j+1].pack_forget()
    lst[j].pack()

    if j > 7:
        j = 1
    elif j < 0:
        j = 7

root = Tk()
bad = Button(root,text = ">",command = lambda mas = mas: f(mas)).place(x = 20, y = 0)
bat = Button(root,text = "<",command = lambda menos = menos: f(menos)).place(x = 0, y = 0)
l1 = Label(root , text = 1)
l2 = Label(root , text = 2)
l3 = Label(root , text = 3)
l4 = Label(root , text = 4)
l5 = Label(root , text = 5)
l6 = Label(root , text = 6)
l7 = Label(root , text = 7)
lst = [l1,l2,l3,l5,l6,l7]

root.mainloop()
