Exposing a C API to Python

Download this blogpost from https://codegive.com
in this tutorial, we will explore how to expose a c++ api to python using the pybind11 library. exposing a c++ api to python allows you to leverage the power and efficiency of c++ for performance-critical code while providing a python interface for easy scripting and integration.
before you begin, make sure you have the following prerequisites installed:
you can install pybind11 using pip:
let's start by creating a simple c++ library that we want to expose to python.
suppose we have a c++ source file named mylibrary.cpp:
next, create a cmakelists.txt file to build your c++ library and the python module:
use cmake to build your c++ library:
this will generate a python module file with a .so extension (e.g., mylibrary.cpython-version-platform.so).
now, let's create a python script to test our c++ library.
execute the python script to test your c++ library:
you should see the following output:
congratulations! you have successfully exposed a c++ api to python using pybind11. you can now expand your c++ library and create more complex python bindings for your code.
exposing a c++ api to python allows you to combine the performance of c++ with the ease of use of python. this tutorial covered the basic steps required to create a simple python module from a c++ library. you can build upon this knowledge to expose more complex c++ apis to python and create powerful cross-language applications.
