Python/C API quick start

A quick example of Python 3.10 modules implemented in C using the Python/C API.

make all
python -c "import hello; hello.greet('World')"
python -c "import fib; print(fib.fib(5))"
make clean

Note that the best way to distribute a Python module is to use a setup.py file. The Makefile is here only to debunk Python's magic.

Steps

1. Write a foobarmodule.c C file. Note the #include <Python.h> at the beginning of example files.
2. Compile foobarmodule.c and produce a foobar.so file. See the Makefile for details.
3. Put foobar.so in a folder listed in the Python path.
4. Load the module from Python with import foobar.
