This is a simple tutorial on how to write python extension in C through a process called "wrapping" or creating a Python extension module.
Use the package manager pip to install python-config and apt for installing python3-dev.
pip install python-config
sudo apt-get install python3-devTo compile this you will need the GNU C compiler Collection gcc
sudo apt-get install build-essential gcc
gcc add.c $(python3-config --includes) -shared -fPIC -o addnums.so
OR
gcc -o addnums.so -shared -fPIC add.c -I/path/to/python/include -lpython3.ximport addnums # make sure you are in same directory as addnums.so
result = addnums.add_numbers(5, 4)
print(result) # Output: 9addnums/
