Python - Tkinter how to close window after button is pressed?
So there is a first window for the user to log into. Once the user has logged in they can start the game by clicking the "continue" button. The command of this button is set to the function con which should close the window using the window.destroy() function however whenever I try to click it I always receive an error stating "window is not defined"
