I installed Python 3.7 for my Mac Book Pro and in Wing101 it still uses Python 2.7.. anyone who can help me out?
In Wing 101, you can set the Python being used in the Configure Python dialog from the Edit menu, by setting the Python Executable. Wing 101 version 6+ should really be finding and using the latest Python installation, although maybe it's installed in a place that it isn't found automatically. Wing version 5 prefers Python 2 because it's fairly old and that made more sense at the time.
