title: tkinter and time.sleep
body: <p>I am trying to delete text inside a text box after waiting 5 seconds, but instead the program wont run and does sleep over everything else. Also is there a way for me to just make my textbox sleep so i can run other code while the text is frozen?</p>
  
  <pre><code>from time import time, sleep
  from Tkinter import *
  
  def empty_textbox():
      textbox.insert(END, 'This is a test')
      sleep(5)
      textbox.delete("1.0", END)
  
  root = Tk()
  
  frame = Frame(root, width=300, height=100)
  textbox = Text(frame)
  
  frame.pack_propagate(0)
  frame.pack()
  textbox.pack()
  
  empty_textbox()
  
  root.mainloop()
  </code></pre>
