How do I make a tkinter button destroy itself?

Question

I made this program in Tkinter in python where a small window pops up when the code is run and a start button would pop up and make the window full screen and show the content after. I want to make the button destroy itself after I press it so it makes a fullscreen and removes the button. I am still a beginner and would like the answer to be simple. The solution I am looking for is to maybe destroy the button completely(preferred) or move it way out of sight in the fullscreen window. Here is the code:

import Tkinter as w
from Tkinter import *

w = Tk()

w.geometry("150x50+680+350")
def w1():
    w.attributes("-fullscreen", True)
    l1 = Label(w, text = "Loaded!", height = 6, width = 8).pack()
    global b1
    b1.place(x = -10000, y = -10000)



b1 = Button(w, text = "Start", height = 3, width = 20, command = w1).place(x = 0, y = 10)
b2 = Button(w, text = "Exit", command = w.destroy).place(x = 1506, y = 0)

w.mainloop()

As you can see I want to make button one destroy itself.

The better plan is just to hide the button, in case you want to put thing back to their original state. You do that with `b1.place_forget()`. — Tim Roberts, Mar 14 '21 at 20:17

Try this:

import tkinter as tk # Use `import Tkinter as tk` for Python 2

root = tk.Tk()
root.geometry("150x50+680+350")

def function():
    global button_start
    root.attributes("-fullscreen", True)
    label = tk.Label(root, text="Loaded!", height=6, width=8)
    label.pack()
    button_start.place_forget() # You can also use `button_start.destroy()`



button_start = tk.Button(root, text="Start", height=3, width=20, command=function)
button_start.place(x = 0, y = 10)
button_exit = tk.Button(root, text="Exit", command=root.destroy)
button_exit.place(x=1506, y=0)

root.mainloop()

Try:

b1.place_forget()

This will essentially "forget" about the button and hide it from view.

Edit: If you are getting the error that b1 is None try:

b1 = Button(w, text = "Start", height = 3, width = 20, command = w1)
b1.place(x = 0, y = 10)

You need to add the b1.place() option at the bottom for this to work

This won't work and will raise `AttributeError: 'NoneType' object has no attribute 'place_forget'`. You have to fix the problem with `b1` always being `None` – TheLizzard Mar 14 '21 at 20:35
