The Python C API has become so verbose that I recommend against using it directly. Recently I mapped a few external libraries using Nanobind, and the result was significantly more concise. Nanobind uses the type system of modern C++ (17 and above) to provide most argument conversions, Mapping C functions is typically just a few lines of code. It also provides a great way to map C++ constructs such as classes, exceptions, and standard containers. Nanobind is by the same author that started pybind11, used by Tensorflow and PyTorch. The web site [1] contains a bit more of the rationale. [1] https://nanobind.readthedocs.io/en/latest/why.html https://nanobind.readthedocs.io/en/latest/why.html
