Is Python and scripting allowed in Inventor?

I've recently watched several videos of python scripting inside of Fusion 360, just wondering if IV allows this along with iLogic, vb and API?

Python scripting in Inventor is not officially supported. But because Inventor API is based on COM, you can communicate with API from any environment which supports COM. Include Python. Because the communication between Python and Inventor is out-of-process I expect the API calls will be much slower then in-process call (like add-ins).

I created this proof of concept script. It worked but I found it not very useful.
