title: Python 3, Tkinter, How to update button text
body: <p>Im trying to make it so that when the user clicks a button, it becomes "X" or "0" (Depending on their team). How can I make it so that the text on the button is updated? My best idea so far has been to delete the buttons then print them again, but that only deletes one button. Here's what I have so far:</p>
  
  <pre><code>from tkinter import *
  
  BoardValue = ["-","-","-","-","-","-","-","-","-"]
  
  window = Tk()
  window.title("Noughts And Crosses")
  window.geometry("10x200")
  
  v = StringVar()
  Label(window, textvariable=v,pady=10).pack()
  v.set("Noughts And Crosses")
  
  def DrawBoard():
      for i, b in enumerate(BoardValue):
          global btn
          if i%3 == 0:
              row_frame = Frame(window)
              row_frame.pack(side="top")
          btn = Button(row_frame, text=b, relief=GROOVE, width=2, command = lambda: PlayMove())
          btn.pack(side="left")
  
  def PlayMove():
      BoardValue[0] = "X"
      btn.destroy()
      DrawBoard()
  
  DrawBoard()
  window.mainloop()
  </code></pre>
