It appears Tkinter.tkinter was changed to tkinter._tkinter in Python 3. Compare these docs from Python 2 with these from Python 3. Also, dooneevent is no longer in tkinter._tkinter, but is still a member of the Tk (aka root) object.

So change your code to

def keys_pressed(d_o_e=lambda arg: _root_window.dooneevent(arg),
        d_w=tkinter._tkinter.DONT_WAIT):

This takes advantage of the fact that in your linked code _root_window is global, so while _root_window is not available when the class is defined, it will be available when the lambda is run.
