Right -- labels don't support an insert method, which is special
to entry and text widgets only.  To set a label widget's text,
just as to set the text on most other widgets, you can use any
way to set the configuration option named 'text' of the widget:
most typical and useful,

    w.config(text='new text')

BTW, to get a configuration option of a widget, for example its
text, w.cget('text') is typical and useful.

This call set the TCL variable named 'myvar' to the new value
and does not affect widget w.

Perhaps what you want to do is, rather:

    s = Tkinter.StringVar()
    w.config(textvariable=s)

and then

    s.set('new text')

will indeed affect the text displayed on the label.
