One of the easiest ways to call C++ from Python is by using Boost.Python. Boost.Python is a library that provides seamless interoperability between Python and C++. It allows you to expose C++ classes, functions, and objects to Python with minimal changes to your existing C++ code. This makes it especially useful when you want to wrap third-party C++ libraries.
The library employs advanced metaprogramming techniques to simplify the process, essentially making the wrapping code look like a declarative interface definition. While it might feel a bit heavy for simpler use cases, its robustness makes it an excellent choice for complex projects where precision and functionality matter. If you’re new to call C++ from Python techniques, Boost.Python offers extensive documentation and community support to help you get started.
