[Tutor] label widgets: double buffering, clearing label text

[gmlloyd]

Good afternoon.

In "An Introduction to Tkinter",  Fredrik Lundh states (section 30 on
Labels): "Labels are used to display texts and images. The label widget
uses double buffering, so you can update the contents at any time,
without annoying flicker."

Does anyone know how to use label widgets in this way?

How about simply clearing label widget text in order to update the text?

thank you,
