Is tkinter a good starting point with graphics in python

Answer 1

Tkinter is a starting point for Graphical User Interface. How good it is is subjective: I personally prefere WXWidgets or GTK as it can blend with the underlying OS style.

For graphics you can look at pygame, graphics, py3D as a starting point.

WXwidgets better GUI
Qt even better GUI
