This is very inaccurate.  From the first line of the second paragraph
at your link, "The tkinter package is a thin object-oriented layer on
top of Tcl/Tk."

Tk is very closely tied to Tcl (in fact a significant fraction of Tk
is implemented in Tcl), and a Tcl interpreter (of the exact same
version) is required to use Tk.  Python's tkinter package dynamically
links to libtcl and libtk to embed a Tcl interpreter, and all GUI
interactions are handled by Tcl calling Python callbacks.
