You aren't actually setting the value. check is an object, and it won't ever be identical to 0. Basically, you want to compare check.get() . Try this:

def go():
        print(check.get())
        if(check.get() == 0):

                print("off")

                w.delete(ALL)
                tegnefladen()
                update()

        else:

                print("on")
                update()
