Initial Query

I want to call some C code from python on a linux machine. Specifically, I want to be able to run python3 -c 'import magic; print(magic.do_add(3, 4))' and have it give me the sum of these numbers. Here, do_add should be a C function that adds two integers. Please give me a complete set of instructions for how to make this run, so that when I run this code as-is it will work.

# Creating a Python C Extension for Addition Here's a complete guide to create a simple C extension for Python that adds two integers: ## Step 1: Install prerequisites 

1
2
sudo apt-get update
sudo apt-get install -y python3-dev gcc
## Step 2: Create the C source file Create a file named `magic.c` with this content:

#include <Python.h>

static PyObject *do_add(PyObject *self, PyObject *args) {
    int a, b;
    
    // Parse the arguments from Python
    if (!PyArg_ParseTuple(args, "ii", &a, &b)) {
        return NULL;
    }
    
    // Compute the sum
    int result = a + b;
    
    // Return the result as a Python object
    return PyLong_FromLong(result);
}

// Method definitions
static PyMethodDef MagicMethods[] = {
    {"do_add", do_add, METH_VARARGS, "Add two integers."},
    {NULL, NULL, 0, NULL}  // Sentinel
};

// Module definition
static struct PyModuleDef magicmodule = {
    PyModuleDef_HEAD_INIT,
    "magic",   // Module name
    NULL,      // Module documentation
    -1,        // Size of per-interpreter state
    MagicMethods
};

// Module initialization
PyMODINIT_FUNC PyInit_magic(void) {
    return PyModule_Create(&magicmodule);
}
## Step 3: Create the setup script Create a file named `setup.py` with this content: 
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
from setuptools import setup, Extension

module = Extension('magic', sources=['magic.c'])

setup(
    name='magic',
    version='1.0',
    description='A module for adding two integers',
    ext_modules=[module]
)
## Step 4: Build and install the extension You have two options: ### Option A: Install the module (system-wide or in your user directory) 
1
2
3
4
5
# For system-wide installation (may require sudo)
python3 setup.py install

# OR for installing in your user directory
python3 setup.py install --user
### Option B: Build the module in-place (if you don't want to install it) 
1
python3 setup.py build_ext --inplace
If you choose Option B, you'll need to run your Python script from the directory containing the built module. ## Step 5: Test the module Now you can run: 
1
python3 -c 'import magic; print(magic.do_add(3, 4))'
And it should output: 
1
7
That's it! You've successfully created, built, and used a Python C extension.

    int a, b;
    
    // Parse the input arguments
    if (!PyArg_ParseTuple(args, "ii", &a, &b))
        return NULL;
    
    // Add the numbers and return the result
    return PyLong_FromLong(a + b);
}

// Define the methods table
static PyMethodDef MagicMethods[] = {
    {"do_add", do_add, METH_VARARGS, "Add two integers."},
    {NULL, NULL, 0, NULL}  // Sentinel
};

// Define the module
static struct PyModuleDef magicmodule = {
    PyModuleDef_HEAD_INIT,
    "magic",   // Module name
    NULL,      // Module documentation
    -1,        // Size of per-interpreter state or -1
    MagicMethods
};

// Initialize the module
PyMODINIT_FUNC PyInit_magic(void) {
    return PyModule_Create(&magicmodule);
}
## Step 2: Create a setup file Create a file named `setup.py` with the following content:

from setuptools import setup, Extension

setup(
    name='magic',
    version='1.0',
    description='Simple module with an add function',
    ext_modules=[module]
)
## Step 3: Build the extension Run this command to build the extension: 
1
python3 setup.py build_ext --inplace
This will compile your C code and create a file called `magic.cpython-XX-XXX.so` in your current directory (where XX-XXX varies depending on your Python version and system architecture). ## Step 4: Test the module Now you can run your desired command: 
1
python3 -c 'import magic; print(magic.do_add(3, 4))'
This should output: 
1

## Troubleshooting If you encounter errors: 1. Make sure you have the Python development headers installed: 
1
2
3
   sudo apt-get install python3-dev  # For Debian/Ubuntu
   sudo dnf install python3-devel    # For Fedora/RHEL
2. You may need to install build tools: 
1
2
3
   sudo apt-get install build-essential  # For Debian/Ubuntu
   sudo dnf groupinstall "Development Tools"  # For Fedora/RHEL
3. If you get import errors, ensure the `.so` file is in your current directory when running the Python command. That's it! You've successfully created a Python extension in C that can add two numbers.
