Hi im trying to use key bind on Tkinter to call this function
def Start():

ent['text'] = i
time.sleep(1)
root.update()
ent['text'] = 'Time Out!'
root.update()
i know the function is ok as i have assigned a button and i calls
the function as i expect
but
root.bind('<a>',Start)
gives the following error
Exception in Tkinter callback
Traceback (most recent call last):

Use
def Start(event):

BTW. functions, unlike classes should be all lower-case.
