How can I use Python implementations of a C class within a C program?

How can I implement a C class in Python, to be called by C ?

This question asks how to create a C class interface that can be implemented in Python, allowing the Python implementation to be used in a larger C program.

To expose the C interface to Python, SWIG is used with the "director" feature enabled for cross-language polymorphism. This enables Python implementations to override parts of the interface.

The second part involves embedding Python in the C application. This is achieved using the Python C API, allowing Python code to be executed and objects to be created.

Finally, a helper function is introduced to convert the PyObject (Python object) representing the Python implementation into a myif (C interface pointer), allowing the C program to call methods on the Python implementation.

With these steps, Python implementations of the C interface can be used seamlessly in the C program, as if they had been written in C itself.
