Another popular option to call C++ from Python is pybind11. It’s a lightweight, header-only library that’s considered a modern alternative to Boost.Python. Pybind11 focuses on simplicity and offers seamless integration with modern C++ (C++11/14/17), making it ideal for developers already working in that ecosystem.
One key benefit of pybind11 is its concise syntax, allowing you to write clean and manageable binding code without needing an extensive understanding of the library itself. It also supports advanced features like handling exceptions, managing smart pointers, and integrating NumPy arrays directly. If you’re working with a straightforward C++ library or need a lightweight solution to quickly call C++ from Python, pybind11 is a fantastic choice.
