python-cpp-extension

Goal

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

Requirements

• python3-dev or python3-devel python development package
• C++ compiler

Build and install

pip3 install src/ will build and install C++ extension.

How to use

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).

Benchmarking

python3 -m pytest tests/test_benchmark.py --verbose

Files

• src/cpp_impl/ - C++ implementation and header file with declaration of SieveOfEratosthenes function
• src/setup.py - setuptools file to easily build and install the extension
• src/cython_wrapper/ - Cython wrapper
• src/cpython_wrapper.cpp / CPython wrapper

tests/test_benchmark.py - simple file to benchmark the extension
