The Python update will be part of the pre-EP patch. We haven't been told outright that the Terrain tools and Fashion career will be too, but I think that's safe to presume, given past practice:
Hi all,
Heads up that this Python upgrade will be included as part of the Base Game patch for Get Famous. That pack is released on November 16, as many of you know the Base Game patches usually arrive a few days prior to the pack release. So expect the patch to arrive around that time.
