While I agree that creating a Tk instance explicitly is preferable tkinter will create one if you don't: >>> import tkinter >>> tkinter._default_root is None True >>> frame = tkinter.Frame() >>> tkinter._default_root <tkinter.Tk object at 0x7f751b0c65f8> >>> frame.master is tkinter._default_root True -- https://mail.python.org/mailman/listinfo/python-list
