I have been working my way through a Python 3 book and got to the
chapter on tkinter. The following is a segment of a example program that
# the views
frame = tkinter.Frame(window)
button = tkinter.Button(frame, text='Up', command=click_up)
button = tkinter.Button(frame, text='Down', command=click_down)
label = tkinter.Label(frame, textvariable=counter)
when I first looked at it I thought it would not work, thinking that the
second reference to button = would over write the first one. Obviously
that is wrong because the program does work. Could someone explain to
me why it works?
