tkinter canvas mvc

[Gigs_]

Hi all!

I have just finished my tkinter text editor, learning tkinter purpose.

Now I want to learn canvas so I want to make my paint program, I think that this 
will be the best to do over model-view-controler pattern which I need to learn also.

Is there any good tutorial for mvc in python or can someone explain me little 
bit about mvc?
or maybe some code snippet in mvc, that will be nice.

Thanks in advance!
