Syntax Highlighting in a tkinter Text widget

[Nicholas Cannon]

Hey guys Im working on an open source text 
editor(https://github.com/nicodasiko/Text-Config-2) and I would like to add 
syntax highlighting(mainly for python code). I have built the editor in python 
and the text input is a Text tkinter widget. I know how to add tags and 
highlight things  but Im not sure on how to constantly update the highlighting.
