tkinter.TclError: bad window path name "!button"

[deanhystad]

denied() destroys the button. Maybe you want pressing button_1 to call move_button_1()?

import tkinter as tk
import random
 
root = tk.Tk()
root.geometry("600x600")
 
def move_button_1():
    button_1.place(
        x=random.randint(0, root.winfo_width() - button_1.winfo_width()),
        y= random.randint(0, root.winfo_height() - button_1.winfo_height())
    )

button_1 = tk.Button(root, text='Não', command=move_button_1)
button_1.pack()

root.mainloop()
