tkinter

[BashBedlam]

This should help:

from tkinter import Tk, Button
button_tries = -1

def change_button (event) :
	global button_tries
	tries = ('Second', 'Third')
	button_tries += 1
	if button_tries <= 1 :
		button.configure (text = f'{tries [button_tries]} Try')
 
window = Tk ()
button = Button (window, text = 'First Try')
button.pack (padx = 10, pady = 10)
window.bind ('<Return>', change_button)
window.mainloop ()

Press Return to change the button text.
