title: Python/Tkinter How to update information in grid
body: <p>I'm running Python 3.2.2 and writing some code to test sockets. For the ease of testing, I'm using Tkinter to add a GUI interface. What I have yet to figure out is how to update the information in the grid I'm using. I want to update "host2" and "port2" in the functions "change1" and "change3" in the following code:</p>
  
  <pre><code>import socket
  from tkinter import *
  import tkinter.simpledialog
  
  root = Tk()
  root.title("Server")
  root.iconbitmap("etc.ico")
  root.geometry("350x100+200+200")
  frame = Frame(root)
  host1 = Label(frame,text="Host: ").grid(row=0,column=0)
  port1 = Label(frame,text="Port: ").grid(row=1,column=0)
  HOST = 'localhost'
  PORT = 11111
  STATUS = 'EMPTY'
  host2 = Label(frame,text=HOST,width=10).grid(row=0,column=1)
  port2 = Label(frame,text=PORT,width=10).grid(row=1,column=1)
  status1 = Label(root,text=STATUS)
  status1.pack(side=RIGHT,padx=2,pady=2)
  
  def change1():
      global HOST
      HOST= tkinter.simpledialog.askstring(title="Host",prompt="Enter the IP of the Host.")
      host2.grid_forget()
  def change3():
      global PORT
      PORT= tkinter.simpledialog.askinteger(title="Port",prompt="Enter the Port of the IP.")
      port2.grid_forget()
  def go1():
      global HOST
      global PORT
      home = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
      home.bind((HOST, PORT))
      home.listen(1)
      conn, addr = home.accept()
      print (addr)
      while 1:
          data = conn.recv(1024)
          if not data: break
          global STATUS
          STATUS = data.decode('UTF-8')
          conn.send(bytes('Received "Hello World"','UTF-8'))
      conn.close()
      global status1
      status1.pack_forget()
      status1.pack(side=RIGHT,padx=2,pady=2)
  
  change = Button(frame, text="Change Host", width=10,command=change1).grid(row=0,column=2)
  change2 = Button(frame, text="Change Port", width=10,command=change3).grid(row=1,column=2)
  go = Button(frame, text="GO!",command=go1,width =10).grid(row=2,column=2)
  frame.pack(side=LEFT)
  
  mainloop()
  </code></pre>
  
  <p>Any help on the matter would be much appreciated! Thanks!</p>
