WebTo build your Python bindings with Cython, you’ll follow similar steps to those you used for CFFI and PyBind11. You’ll write the bindings, build them, and then run Python code to call them. Cython can support both C and C++. For this example, you’ll use the cppmult library that you used for the PyBind11 example above.
