[Tutor] Adding a GUI

[wormwood_3]

Hi all,

I am just starting to learn GUI programming, with wxPython. I have a script that that I have developed to a useful point, and I want to add a GUI to it. I am a little unsure as the the best approach to this. The script heretofore was just run at the command line. Would it make sense to add an option in the same script to have it run in "graphical mode", which would trigger the wxPython code I would add in, and otherwise use the same logic? 

More generally: Anyone have any tips on adding a GUI to a pre-existing script in a way that minimizes repetition of logic? I would rather not make a separate script that only used wxPython, and I do not think I have to, but perhaps there are good reasons to, etc.

Thanks,
Sam
