Tkinter removing old Frame when updated

I tried this, and this method didn't help either.

I have a bit of code that shows current weather and temperature, and want it to obviously update. I manage to do the update, but it adds the updated frame underneath the old one. I can't seem to find a way to remove the old frame and replace it with the updated one.

Here's the extract of my code:

def refresh():
    Label(framewet, text=weatherstring + ",   " + temperature + "°",
          bg='black', fg='white', font=("avenir", 35)).pack()
    framewet.pack(side='right', fill='y')
    window.after(3000, refresh) # 3 secs just for debug
    # framewet.destroy() does not work, nor .pack_forget()

# window is the wholw window, may known as root.Tk()


if __name__ == "__main__":
    window.after(0, refresh)
    window.mainloop(0)

Thank you.

Instead of destroying your frame you can simply update the label. This can be done with defining the label on init and then just updating it with config() on a loop.

Here is a simple counter with your code.

from tkinter import *


def refresh():
    global counter, label
    counter += 1
    label.config(text="Counter: {}".format(counter))
    window.after(1000, refresh)

if __name__ == "__main__":
    window = Tk()
    counter = 1
    framewet = Frame()
    framewet.pack(side='right', fill='y')
    label = Label(framewet, text="Counter: {}".format(counter), bg='black', fg='white', font=("avenir", 35))
    label.pack()
    refresh()
    window.mainloop()
