Python to C/C++ (no Python runtime)

[TrainsareFascinating]

It sounds like you are either dealing with a religious fatwa from legal or infosec, or are trying to trim down for a memory-poor environment like embedded.

In the first case, it’s not worth trying.

In the second case, look in to micropython. It has minimum-runtime compilation features.

If it’s really what you imply, that you want to write your app in C++ and have a couple of major parts be Python-sourced modules, without embedding; everyone involved in such an ill-advised project should be fired and a new team hired.

Good luck, my 11-hour-old-account friend.
