Hello All, While trying to learn Python I developed a small game, Text Text. It has rough edges and may not meet your class. However, by reviewing it you'll be helping me to advance.

Hello All,
Say I have the below(code), I would want the message to last say 30
seconds and afterwards disappear. I won't want the user to be the one to
enable it to disappear.
Basically, what I want is to be able to show the user some message , and
after some seconds, the message goes away

import tkMessageBox
top = Tkinter.Tk()
def hello():
tkMessageBox.showinfo("Say Hello", "Hello World")
B1 = Tkinter.Button(top, text = "Say Hello", command = hello)

top.mainloop()
