How do I bind C++ functions to Python?

You can use libraries like Boost.Python or pybind11 to bind C++ functions to Python.

Can you give me a simple example using pybind11?

Sure! Here's a basic example:

#include <pybind11/pybind11.h>

int add(int a, int b) {
    return a + b;
}

PYBIND11_MODULE(example, m) {
    m.def("add", &add);
}

This binds the add function so you can call it from Python.

What do I need to install to use pybind11?

You can install pybind11 using pip with the command pip install pybind11. Make sure you have a C++ compiler set up as well.

Are there any performance considerations I should be aware of?

Yes, while binding C++ to Python can improve performance for compute-intensive tasks, there may be overhead in data conversion between the two languages.
