On my end (east coast US), I hear the Python/data/analytics things a lot but haven't directly encountered those companies. Python was at least previously big in a lot of local shops doing a lot of systems programming type stuff (management apps) -- including folks like Red Hat and HP, including my old one (Ansible). Startups are still highly likely to use it. There are enough Django shops around, including at least one major Django consultancy-type shop, but it feels like slightly more (but not much more) rails on the web side. I'm not plugged into the industry biotech to know how much Python is floating around, but I think it's probably pretty common, just that those folks travel in slightly different circles and we don't cross polinate enough. "Is anyone actually adopting Python 3 as their default yet?" Almost certaintly someone has, the real question is what percentage and what characterizes them :)
