David I. has a fantastic blog post on using Python4Delphi with C++Builder.
https://davidiontools.com/2020/10/13/using-python4delphi-with-cbuilder-vcl-applications/

This was inspired by our previous webinars on the topic. and is the result of his collaboration with Kiriakos (AKA PyScripter), the maintainer of Python4Delphi, who also made some changes in the library to work better with C++Builder.

By popular request, David and Kiriakos have also agreed to run a Python for C++ developers webinar where you can learn to leverage Python from your favorite C++ developer tools.
