How can I use Cython to interface with C++?

How can I use Cython to interface with C++?

You can use Cython to create Python bindings for C++ code. First, you'll need to write a .pyx file that declares the C++ functions you want to use.

What are the steps to create a .pyx file?

Start by importing the C++ headers in your .pyx file. Then, declare the C++ functions using the 'cdef' keyword. Finally, compile it using a setup.py script.

Can you give me an example of a simple C++ function and how to bind it?

Sure! If you have a C++ function like int add(int a, int b), you would declare it in your .pyx file as cdef extern from 'your_cpp_file.h': int add(int a, int b). Then, you can call it directly in Python.

What do I need to install to get started?

You'll need Cython, a C++ compiler, and Python development headers. You can install Cython via pip with pip install cython.
