There is only 1 Python module named example. However, there are 2 extensions behind. One (example.c) is by C, and the other is by C++ with STL (stl_example.cpp).

The key secret is in setup.py.

There is also a Makefile to explain how SWIG works.

Usage

virtualenv -p python3 .env
source .env/bin/activate
pip install -r requirements.txt
pip install -e .
pytest

The compilation and packaging happens in pip install -e .
