Using Tk code directly from Tkinter

[Volker Dobler]

Hello,

I'd like to use Tk code directly in Tkinter:
gnuplot can produce plot output as Tk commands stored
in a file 'plot.tk'. Basically a procedure gnuplot is defined
which needs a canvas widget. Calling this procedure will
draw the plot in the given canvas.  Is it possible to feed
such a file into Tk via Tkinter or would it be easier to
write a new terminal for gnuplot which outputs Tkinter
code to be execed in Python?
