If you press any key on your keyboard, this small Tkinter GUI program will tell you which key and what type of key has been pressed. Great for applications where a simple key stroke is required.

from Tkinter import *

root = Tk()
prompt = '      Press any key      '
label1 = Label(root, text=prompt, width=len(prompt), bg='yellow')

def key(event):
    if event.char == event.keysym:
        msg = 'Normal Key %r' % event.char
    elif len(event.char) == 1:
        msg = 'Punctuation Key %r (%r)' % (event.keysym, event.char)
        msg = 'Special Key %r' % event.keysym

root.bind_all('<Key>', key)
