Python-Tkinter: How do I update a whole segment?

I have a segment in my GUI that creates a varying number of labels using a for-loop. Furthermore, I have a button that’s supposed to delete all of these labels and recall the for loop with new information.

However, I can’t figure out how to make my button do that. Specifically do both of these actions together.

I have tried to delete the frame containing the labels with frame.destroy() like this:

import tkinter

root = tkinter.Tk()

frame = tkinter.Frame(root)
frame.pack()

def create():
    for i in 'test':
        tkinter.Label(frame, text='TEST').pack()
create()

def command():
    frame.destroy()
    # frame = tkinter.Frame(root)
    # frame.pack()
    create()

tkinter.Button(root, text='Button', command=command).pack()

root.mainloop()

That successfully deletes the labels but I can’t figure out how to create new ones.

Same thing with putting the for-loop in a class and deleting the object and creating a new one.

Is there another option than deleting each individual label? I figure that would be rather complicated as each label would need an individual variable name. Haven’t tried that yet, tho.

Thanks :)

You have to use global frame in each function so that they use the same variable:

import tkinter

root = tkinter.Tk()

frame = tkinter.Frame(root)
frame.pack()

def create():
    global frame
    for i in 'test':
        tkinter.Label(frame, text='TEST').pack()
create()

def command():
    global frame
    frame.destroy()
    frame = tkinter.Frame(root)
    frame.pack()
    create()

tkinter.Button(root, text='Button', command=command).pack()

root.mainloop()

Since you just use .pack() the button moves to the top after, but this should work as intended.
