return a + b;
}

int a, b;
if (!PyArg_ParseTuple(args, "ii", &a, &b)) {
return NULL;
}
return PyLong_FromLong(do_add(a, b));
}
static PyMethodDef MagicMethods[] = {
{"do_add", wrap_do_add, METH_VARARGS, "Add two integers"},
{NULL, NULL, 0, NULL}
};
static struct PyModuleDef magicmodule = {
PyModuleDef_HEAD_INIT,
"magic",
NULL,
-1,
MagicMethods
};
PyMODINIT_FUNC PyInit_magic(void) {
return PyModule_Create(&magicmodule);
}
|
2. Compile the C code:
Compile the `magic.c` file to create a shared library using the following command:
| gcc -shared -o magic.so -fPIC magic.c -I /usr/include/python3.8
|
3. Use the shared library in Python:
Create a Python script (e.g., `test.py`) with the following content:
| import ctypes
magic = ctypes.CDLL('./magic.so')
do_add = magic.do_add
do_add.argtypes = [ctypes.c_int, ctypes.c_int]
do_add.restype = ctypes.c_int
print(do_add(3, 4))
|
4. Run the Python script:
Run the Python script using the following command:
This will output the sum of the two numbers (3 + 4), which is 7.
This setup allows you to call the C function `do_add` from Python and get the desired result.

Output
To call C code from Python, you can use the ctypes library which allows calling functions in shared libraries. Here's a step-by-step guide on how to achieve this:
Step 1: Write the C code
Create a new C file called `magic.c` with the following content:
| #include <stdio.h>
int do_add(int a, int b) {
return a + b;
}
|
Step 2: Compile the C code
Compile the `magic.c` file into a shared library using the following command:
| gcc -shared -o libmagic.so -fPIC magic.c
|
This will generate a shared library file called `libmagic.so`.
Step 3: Write the Python code
Create a new Python file called `magic.py` with the following content:
| from ctypes import CDLL
libmagic = CDLL('./libmagic.so')
def do_add(a, b):
return libmagic.do_add(a, b)
|
Step 4: Run the Python code
Now you can run the Python script using the following command:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This will output `7`, which is the sum of 3 and 4 calculated by the C function.
Make sure that the `libmagic.so` file is in the same directory as the `magic.py` file, or you can specify the full path to the library file in the `CDLL` function call in the Python code.
By following these steps, you should be able to call C code from Python on a Linux machine as desired.

Output
To call C code from Python, you can use the ctypes library in Python. Here are the steps to achieve this:
1. Write the C code:
Create a C file, let's call it `magic.c`, with the following code for the `do_add` function:
| #include <stdio.h>
int do_add(int a, int b) {
return a + b;
}
|
2. Compile the C code:
Compile the `magic.c` file into a shared library using the following command:
| gcc -shared -o libmagic.so -fPIC magic.c
|
This will create a shared library named `libmagic.so`.
3. Write the Python code:
Create a Python file, let's call it `magic.py`, with the following code:
| import ctypes
# Load the shared library
magic_lib = ctypes.CDLL('./libmagic.so')
# Define the function prototype
do_add = magic_lib.do_add
do_add.argtypes = [ctypes.c_int, ctypes.c_int]
do_add.restype = ctypes.c_int
|
4. Test the code:
Now you can run the following command to test the code:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This command will load the shared library, define the `do_add` function, and print the sum of 3 and 4, which should be 7.
By following these steps, you should be able to call C code from Python on a Linux machine.

Output
To call C code from Python on a Linux machine, you can use the `ctypes` module in Python to load and call C functions from shared libraries. Here's a step-by-step guide on how to achieve this:
1. Write your C code with the `do_add` function that adds two integers. Save this code in a file named `magic.c`:
| #include <stdio.h>
int do_add(int a, int b) {
return a + b;
}
|
2. Compile the C code into a shared library using the following command:
| gcc -shared -o libmagic.so -fPIC magic.c
|
This will create a shared library named `libmagic.so` that contains the `do_add` function.
3. Next, create a Python script that loads the shared library and calls the `do_add` function. Save this code in a file named `magic.py`:
1

3
4
5
6
7
8

16 | import ctypes
# Load the shared library
libmagic = ctypes.CDLL('./libmagic.so')
# Define the argument and return types for the function
libmagic.do_add.argtypes = [ctypes.c_int, ctypes.c_int]
libmagic.do_add.restype = ctypes.c_int
# Call the C function
def do_add(a, b):
return libmagic.do_add(a, b)
# Test the function
if __name__ == '__main__':
print(do_add(3, 4))
|
4. Now, you can run your Python script with the `python3` command to call the C function and print the result:
This should output `7`, which is the sum of `3` and `4`, as calculated by the `do_add` function in your C code.
By following these steps, you should be able to call C code from Python on a Linux machine as requested.

int do_add(int a, int b) {

Save this file as `magic.c`.
2. Compile the C code:
Open a terminal and navigate to the directory where `magic.c` is saved. Compile the C code using the following command:
| gcc -shared -o magic.so -fPIC magic.c
|
This will generate a shared object file `magic.so` which contains the compiled C code.
3. Write a Python wrapper:
Create a Python file with the following code:
| from ctypes import CDLL
magic = CDLL('./magic.so')
def do_add(a, b):
return magic.do_add(a, b)
|
Save this file as `magic.py`.
4. Run the Python code:
You can now run the Python code using the following command:
| python3 -c 'import magic; print(magic.do_add(3, 4))'
|
This will output the sum of 3 and 4, which is 7.
