I m also extremely late to the party  but I ll leave my version of the answer here for others who may have gotten here  like I did  searching for how to hide something that was placed on the screen with the  place   function  and not  pack   neither  grid    In short  you can hide a widget by setting the width and height to zero  like this  widget place anchor  quot nw quot   x 0  y 0  width 0  height 0   To give a bit of context so you can see what my requirement was and how I got here  In my program  I have a window that needs to display several things that I ve organized into 2 frames  something like this   WINDOW - app     FRAME 1 - hMainWndFrame       Buttons and other controls  widgets      FRAME 2 - hJTensWndFrame       other Buttons and controls  widgets    Only one frame needs to be visible at a time  so on application initialisation  i have something like this  hMainWndFrame   Frame app  bg  quot  aababd quot   hMainWndFrame place anchor  quot nw quot   x 0  y 0  width 480  height 320      hJTensWndFrame   Frame app  bg  quot  aababd quot    I m using  place   instead of  pack   or  grid   because i specifically want to set precise coordinates on the window for each widget  So  when i want to hide the main frame and display the other one  along with all the other controls   all i have to do is call the  place   function again  on each frame  but specifying zero for width and height for the one i want to hide and the necessary width and height for the one i want to show  such as  hMainWndFrame place anchor  quot nw quot   x 0  y 0  width 0  height 0  hJTensWndFrame place anchor  quot nw quot   x 0  y 0  width 480  height 320   Now it s true  I only tested this on Frames  not on other widgets  but I guess it should work on everything

I know this is a couple of years late  but this is the 3rd Google response now for  Tkinter hide Label  as of 10 27 13    So if anyone like myself a few weeks ago is building a simple GUI and just wants some text to appear without swapping it out for another widget via  lower  or  lift  methods  I d like to offer a workaround I use  Python2 7 Windows    from Tkinter import     class Top Toplevel       def   init   self  parent  title    How to Cheat and Hide Text            Toplevel   init   self parent          parent geometry  250x250 100 150           if title              self title title          parent withdraw           self parent   parent         self result   None         dialog   Frame self          self initial focus   self dialog dialog          dialog pack         def dialog self parent            self parent   parent          self L1   Label parent text    Hello  World   state   DISABLED  disabledforeground   parent cget  bg            self L1 pack            self B1   Button parent  text    Are You Alive      command   self hello          self B1 pack        def hello self           self L1  state    normal    if   name         main         root Tk          ds   Top root      root mainloop     The idea here is that you can set the color of the DISABLED text to the background   bg   of the parent using   cget  bg    http   effbot org tkinterbook widget htm rendering it  invisible   The button callback resets the Label to the default foreground color and the text is once again visible    Downsides here are that you still have to allocate the space for the text even though you can t read it  and at least on my computer  the text doesn t perfectly blend to the background  Maybe with some tweaking the color thing could be better and for compact GUIs  blank space allocation shouldn t be too much of a hassle for a short blurb   See Default window colour Tkinter and hex colour codes for the info about how I found out about the color stuff

One option  as explained in another answer  is to use pack forget or grid forget  Another option is to use lift and lower  This changes the stacking order of widgets  The net effect is that you can  hide widgets behind sibling widgets  or descendants of siblings   When you want them to be visible you lift them  and when you want them to be invisible you lower them    The advantage  or disadvantage     is that they still take up space in their master  If you  forget  a widget  the other widgets might readjust their size or orientation  but if you raise or lower them they will not    Here is a simple example   import Tkinter as tk  class SampleApp tk Tk       def   init   self   args    kwargs           tk Tk   init   self   args    kwargs          self frame   tk Frame self          self frame pack side  top   fill  both   expand True          self label   tk Label self  text  Hello  world           button1   tk Button self  text  Click to hide label                              command self hide label          button2   tk Button self  text  Click to show label                               command self show label          self label pack in  self frame          button1 pack in  self frame          button2 pack in  self frame       def show label self  event None           self label lift self frame       def hide label self  event None           self label lower self frame   if   name         main         app   SampleApp       app mainloop

For hiding a widget you can use function pack forget   and to again show it you can use pack   function and implement them both in separate functions   from Tkinter import   root   Tk   label Label root text  I was Hidden   def labelactive        label pack   def labeldeactive        label pack forget   Button root text  Show  command labelactive  pack   Button root text  Hide  command labeldeactive  pack   root mainloop

I was not using grid or pack  I used just place for my widgets as their size and positioning was fixed  I wanted to implement hide show functionality on frame  Here is demo from tkinter import   window Tk   window geometry  quot 1366x768 1 1 quot   def toggle graph visibility        graph state chosen show graph checkbox value get       if graph state chosen  0          frame place forget       else          frame place x 1025 y 165  score pixel   PhotoImage width 300  height 430  show graph checkbox value   IntVar value 1  frame Frame window width 300 height 430  graph canvas   Canvas frame  width   300  height   430 scrollregion  0 0 300 300   my canvas graph canvas create image 20  20  anchor NW  image score pixel  vbar Scrollbar frame orient VERTICAL  vbar config command graph canvas yview  vbar pack side RIGHT fill Y  graph canvas config yscrollcommand vbar set  graph canvas pack side LEFT expand True fill BOTH  frame place x 1025 y 165  Checkbutton window  text  quot show graph quot  variable show graph checkbox value command toggle graph visibility  place x 900 y 165  window mainloop    Note that in above example when  show graph  is ticked then there is vertical scrollbar  Graph disappears when checkbox is unselected  I was fitting some bar graph in that area which I have not shown to keep example simple  Most important thing to learn from above is the use of frame place forget   to hide and frame place x x pos y y pos  to show back the content

For someone who hate OOP like me  This is based on Bryan Oakley s answer   import tkinter as tk  def show label        label1 lift    def hide label        label1 lower    root   tk Tk   frame1   tk Frame root  frame1 pack    label1   tk Label root  text  Hello  world   label1 pack in  frame1   button1   tk Button root  text  Click to hide label  command hide label  button2   tk Button root  text  Click to show label   command show label  button1 pack in  frame1  button2 pack in  frame1   root mainloop
