python-cpp-extension

Goal

To create a simple example how to extend Python with C++ extensions.

python3 setup.py build will build the C++ extension.

python3 setup.py install will build and install it.

You can use --user flag to install to the Python user install directory.

First, install the extension. Then you can use it like this:

import cpp_python_extension

print(cpp_python_extension.sieve_of_eratosthenes(11))

This will print all the prime numbers from 1 to 11 (inclusive).

python3 -m pytest test_benchmark.py --verbose

setup.py - setuptools file to easily build and install the extension
sieve.h - header file with declaration of SieveOfEratosthenes function
sieve.cpp - implementation file
sieve_python_wrapper.cpp - wrapper around SieveOfEratosthenes function to create cpp_python_extension module
test_benchmark.py - simple file to benchmark the extension
