root.mainloop()

Answer 1

Your code does not run. Please provide a Minimal, Complete, and Verifiable example .

However, you are using the name "yesbot" for the button and also for the button callback function, the only difference being the case. This may be the root of your problem.

Should than not be the case I'm supplying an example of how hiding a widget can be done.

from tkinter import *

root = Tk()

def hide_button():
    yesbot.grid_forget()

yesbot = Button(text="yes", command=hide_button)
yesbot.grid(row=4,column=4)

root.mainloop()
