Automatically close window after a certain time in Tkinter

In order to close a Tkinter application, we generally refer to close the parent window using the destroy() method. To close the Tkinter window automatically after a certain time limit, we have to use the after(time in ms, callback) method by specifying the time and the callback function which needs to be run after a certain time limit.

Example

#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of tkinter frame win = Tk() #Set the geometry of tkinter frame win.geometry("750x270") #Initialize a Label widget Label(win, text= "This window will get closed after 3 seconds...", font=('Helvetica 20 bold')).pack(pady=20) #Automatically close the window after 3 seconds win.after(3000,lambda:win.destroy()) win.mainloop()

Output

Running the above code will display a window that will get closed after 3 seconds.

The given output window will get closed after 3 seconds which can be modified by changing the value in the after (time, callback) method.
