Tkinter checkbox value

[scratchmyhead]

How do I get the current value of a checkbutton. So if someone checked a box, then how to get the value. Is the value either 1 or 0?

Example:

var5 = IntVar()
    checksmoke = Checkbutton(checkin, text="Smoker", bg="yellow", command=selectsmoke, variable=var5)
    checksmoke.place(x=105, y=420)

The best way to get values from any of the Tk widgets is binding the widget to a variable and using the variable to get and set the widget value.

Could you give me an example on how to do that?

When I click the check button, the var value is always 0. Why is that?

Here is something I been playing around with.
