In the interests of more efficient data transfer between the internal data structures and the Python C-API, please consider this poll concerning the minimum Python version required to run DEVSIM. Please add comments, if needed.
It is straightforward to run a 3.6 script on 3.11. The only issue is that modules written in C/C++ have to be recompiled for the new version, or use the Python stable API. DEVSIM currently works with any intepreter for version 3.6 and higher.
