change background color of button

[ieee488]

Thank you both.

I ended up with

def setBG(button):
    if button['bg'] == 'white':
        button['bg'] = 'yellow'
        button['activebackground'] = 'yellow'
    else:
        button['bg'] = 'white'
        button['activebackground'] = 'white'

where the buttons are created with

aButton = tkinter.Button(Gui, bg='white', activebackground='white')
aButton['command'] = partial(setBG, aButton)

This was something quick, though using class is definitely the better way.
I have a lot to learn with Python.
