Is it possible to call a function from a Tkinter widget.bind and include args???

this calls the printButtonAndCoords function, and passes the
result to the bind function.

(well, to be precise, it gives a TypeError exception)

try this instead:

    Button1.bind("<Enter>", lambda e: printButtonAndCoords(e, "button1"))
    Button2.bind("<Enter>", lambda e: printButtonAndCoords(e, "button2"))

(the lambda statement creates a callable object taking one
argument, which it passes on to the printButtonAndCoords
function)

you might prefer writing this as

    callback = lambda e: printButtonAndCoords(e, "button1")
    Button1.bind("<Enter>", callback)
    callback = lambda e: printButtonAndCoords(e, "button2")
    Button2.bind("<Enter>", callback)

or even:

    def callback(e):
        printButtonAndCoords(e, "button1")
    Button1.bind("<Enter>", callback)

    def callback(e):
        printButtonAndCoords(e, "button2")
    Button2.bind("<Enter>", callback)

hope this helps!
