Clear the window in tkinter

I made a tkinter window in python with some widgets like so:

def createWidgets(self):   

    self.grid(padx=25, pady=25)
    self.start = Button(self)
    self.start["text"] = "Start"
  开发者_如何学Go  self.start["width"]   = "15"
    self.start["height"]   = "1"
    self.start["command"] =  self.start_g            
    self.start.grid(row=0, column=1, pady=5, sticky=N)

The problem is, I want to remove a widget, so I could add something else to this window. I tried remove() grid_forget() and I can get rid of the widget. Is there any way to remove a widget or wipe the window?

You can call grid_forget() on your widget to permanently remove it.

e.g

self.start.grid_forget()

If you wanted to clear the whole window then you could do the same on your main frame.
