Looks like the `XCode` images come with python 2.x pre-installed. Is there a way, other than installing it via `brew`, to use Python 3 on that image? If yes, how would anyone cache that installation so that it doesn’t repeat itself every time?

I should think that merely installing Python 3 would be so quick, it would barely be worth caching. The build servers will be on some pretty fast connections.
