Thanks. Reviewed to 2d30432ae61f062cfb16d1da01fb930ddb344502. Not tested. @Pro-Panda, could you test?

Thanks. Tested using sugar-toolkit-gtk3/@4b294ac

• the activity still calls the Python 2 toolkit code; it should call the Python 3 version
• Following errors were reported while running the activity:

  1529724998.263839 ERROR root: Error saving activity object to datastore

• The extra paranthesis is due to a regex issue in 2to3 (which you'd be presumably using), a possible solution would be to review each change made before comitting; git add -p could help
• Pippy uses telepathy which should be ported to TelepathyGLib; please see updated guide to port activities to Python 3

@Pro-Panda Thanks, working!

@Pro-Panda , I missed to update activity.info so this is calling Python 2 toolkit code I'll fix it
