The '>' symbols got mangled in my previous email, so here is a corrected email.

This sequence fails to find gtk:

saf$ python3
Python 3.7.4 (default, Jul  9 2019, 16:32:37)
[GCC 9.1.1 20190503 (Red Hat 9.1.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
 >>> import gtk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'gtk'

But this sequence works:

saf$ python3
Python 3.7.4 (default, Jul  9 2019, 16:32:37)
[GCC 9.1.1 20190503 (Red Hat 9.1.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
 >>> import gi
 >>> gi.require_version('Gtk', '3.0')
 >>> from gi.repository import Gtk
 >>>

Is there something that I need to install?  I'm a complete python noob.
