You can use forget method on the widget   from tkinter import    root   Tk    b   Button root  text  Delete me   command b forget  b pack    b  command     b forget  root mainloop

You say that you have a list of widgets to change dynamically  Do you want to reuse and reconfigure existing widgets  or create all new widgets and delete the old ones  It affects the answer   If you want to reuse the existing widgets  just reconfigure them  Or  if you just want to hide some of them temporarily  use the corresponding  forget  method to hide them  If you mapped them with pack   calls  you would hide with pack forget    or just forget    calls  Accordingly  grid forget   to hide gridded widgets  and place forget   for placed widgets   If you do not intend to reuse the widgets  you can destroy them with a straight destroy   call  like widget destroy    to free up resources

You simply use the destroy   method to delete the specified widgets like this   lbl   tk Label        btn   tk Button        command lambda  lbl destroy      Using this you can completely destroy the specific widgets

One way you can do it  is to get the slaves list from the frame that needs to be cleared and destroy or  hide  them according to your needs  To get a clear frame you can do it like this   from tkinter import    root   Tk    def clear        list   root grid slaves       for l in list          l destroy    Label root text  Hello World    grid row 0  Button root text  Clear  command clear  grid row 1   root mainloop     You should call grid slaves    pack slaves   or slaves   depending on the method you used to add the widget to the frame

I found that when the widget is part of a function and the grid remove is part of another function it does not remove the label  In this example     def somefunction self       Label self  text      grid row   0  column   0      self text ent   Entry self      self text ent grid row   1  column   0  def someotherfunction self       somefunction text ent grid remove        there is no valid way of removing the Label   The only solution I could find is to give the label a name and make it global   def somefunction self       global label     label   Label self  text          label grid row   0  column   0      self text ent   Entry self      self text ent grid row   1  column   0  def someotherfunction self       global label     somefunction text ent grid remove       label grid remove     When I ran into this problem there was a class involved  one function being in the class and one not  so I m not sure the global label lines are really needed in the above

You can call pack forget to remove a widget  if you use pack to add it to the window    Example   from tkinter import    root   Tk    b   Button root  text  Delete me   command lambda  b pack forget    b pack    root mainloop     If you use pack forget  you can later show the widget again calling pack again  If you want to permanently delete it  call destroy on the widget  then you won t be able to re-add it    If you use the grid method  you can use grid forget or grid remove to hide the widget
