Of course you can assign the command to the button as follows  however  if you are making a UI  it is recommended to assign the same command to the  quot X quot  button  def quit self     Your exit routine    self root destroy    self root protocol  quot WM DELETE WINDOW quot   self quit    Sets the command for the  quot X quot  button   Button text  quot Quit quot   command self quit    No

You can use   root destroy     Or  root quit     If that does not work  change root to what ever your variable was at the start of your program  import tkinter  main   Tk    main destroy    main mainloop

You should use destroy   to close a tkinter window   from Tkinter import    root   Tk   Button root  text  Quit   command root destroy  pack   root mainloop       Explanation   root quit     The above line just Bypasses the root mainloop   i e root mainloop   will still be running in background if quit   command is executed   root destroy     While destroy   command vanish out root mainloop   i e root mainloop   stops   So as you just want to quit the program so you should use root destroy   as it will it stop the mainloop     But if you want to run some infinite loop and you don t want to destroy your Tk window and want to execute some code after root mainloop   line then you should use root quit    Ex   from Tkinter import   def quit        global root     root quit    root   Tk   while True      Button root  text  Quit   command quit  pack       root mainloop        do something

I think you wrongly understood the quit function of Tkinter  This function does not require you to define   First  you should modify your function as follows   from Tkinter import   root   Tk   Button root  text  Quit   command root quit  pack   root mainloop     Then  you should use   pyw  suffix to save this files and double-click the   pyw  file to run your GUI  this time  you can end the GUI with a click of the Button  and you can also find that there will be no unpleasant DOS window    If you run the   py  file  the quit function will fail

In idlelib PyShell module  root variable of type Tk is defined to be global  At the end of PyShell main   function it calls root mainloop   function which is an infinite loop and it runs till the loop is interrupted by root quit   function  Hence  root quit   will only interrupt the execution of mainloop  In order to destroy all widgets pertaining to that idlelib window  root destroy   needs to be called  which is the last line of idlelib PyShell main   function

try this        self parent destroy        self parent quit     maybe you send root like parameter to a frame that you did  so If you want to finish it you have to call your father so he can close it all  instead of closing each one of his children

The easiest way would be to click the red button  leftmost on macOS and rightmost on Windows   If you want to bind a specific function to a button widget  you can do this   class App      def   init   self  master          frame   Tkinter Frame master          frame pack           self quit button   Tkinter Button frame  text    Quit   command   frame quit          self quit button pack     Or  to make things a little more complex  use protocol handlers and the destroy   method   import tkMessageBox  def confirmExit        if tkMessageBox askokcancel  Quit    Are you sure you want to exit             root destroy   root   Tk   root protocol  WM DELETE WINDOW   confirmExit  root mainloop

Illumination in case of confusion     def quit self       self destroy       exit     A  destroy   stops the mainloop and kills the window  but leaves python running  B  exit   stops the whole process  Just to clarify in case someone missed what destroy   was doing  and the OP also asked how to  end  a tkinter program
