Used it a ton in the art departments of vfx and game dev. Im talking about the tools that make assets, not the game engine or a runtime scripting language. More like the stuff launching and running in Maya, or Houdini, or Substance, etc.
Most of this is already highly OO, and there's a lot of interaction with C++. Python is the perfect language for this. There's a lot of rapid interation and gluing many different services and data together. Also you're waiting on file IO or some massive scene graph update all the time so having the tools be slightly slower doesn't matter. Also, at least in vfx, there's mixed Linux/Windows/Mac and it's great for that. ALSO art teams (unlike the programming team) have people who may not be super technical, and Python let's them write tools and scripts more easily. They don't even have to understand OO but you can say "copy this class template and implement these two methods" and they can write tools that "work" in the pipeline.
It's honestly a godsend. Before the industry settled on Python, every program had its own proprietary scripting language and some were quite limited. Their C++ APIs are all different, of course. So now everyone just ships with a Python interpreter, you manage launching each app so you can control PYTHONPATH and you're golden.
