Creating a Tkinter Button to 'clear' Output -

i have basic program spits out string of values, not quite sure how clear these values. @ moment have set exit window , start new 1 i'm not rewriting on new values time. there simple way add button says 'clear' , that? code below:

def create_widgets(self):         self.entrylabel = label(self, text="please enter list of numbers:")         self.entrylabel.grid(row=0, column=0, columnspan=2)          self.listentry = entry(self)     self.listentry.grid(row=0, column=2, sticky=e)      self.entrylabel = label(self, text="please enter index value:")     self.entrylabel.grid(row=1, column=0, columnspan=2, sticky=e)      self.indexentry = entry(self)     self.indexentry.grid(row=1, column=2)      self.runbttn = button(self, text="run function", command=self.psifunction)     self.runbttn.grid(row=2, column=0, sticky=w)      self.answerlabel = label(self, text="output list:")     self.answerlabel.grid(row=2, column=1, sticky=w)      self.clearbttn = button(self, text="clear output", command=)     self.clearbttn.grid(row=3, column=0, sticky=w)  def clear():     config.self.entrylabel(text="")      tk.button(text="write", command=write).grid()     tk.button(text="clear", command=clear).grid()      self.clearbttn = button(self, text="clear output", command=clear)     self.clearbttn.grid(row=3, column=0, sticky=w) 

you kinda asked 2 different questions here. i'll address first, since came in with. change label, update text using config method:

import tkinter tk  root = tk.tk()  label = tk.label() label.grid()  def write():     label.config(text="blah"*6)  def clear():     label.config(text="")  tk.button(text="write", command=write).grid() tk.button(text="clear", command=clear).grid()  root.mainloop()
