Call the python function from C compiler

[shashi59]

from ctypes import *
class HELLO(Structure):
    _fields_=[("a",c_int),
              ("b",c_int)]
x=input()
y=input()
hai=HELLO(x, y)
print hai.a,hai.b

This my code in python.now i can call the function HELLO(x,y) from c compiler and also can i see the output of this code in C compiler window...Is it possible....If its possible plz give idea...

Not possible. ctypes is used for calling C library functions with C type arguments FROM Python.

ok....Is there any possible to write structure in c wrapper code
Example this is my c wrapper code for factorial ok....

#include <Python.h>

int fact(int n)
{
    if ((n == 0)||(n==1))
        return 1;
    else
        return fact(n*fact(n-1));
}

static PyObject* fact(PyObject* self, PyObject* args)
{
    const char *command;
    int n;

    if (!PyArg_ParseTuple(args, "i", &n))
        return NULL;

    return Py_BuildValue("i", fact(n));
}

static PyMethodDef FactMethods[] = {
    {"fact", fact, METH_VARARGS, "Calculate the Factorial of given numbers."},
    {NULL, NULL, 0, NULL}
};

PyMODINIT_FUNC
initfact(void)
{
    (void) Py_InitModule("fact", FactMethods);
}

here i could use fact() function calling .......instead of fuction Is there any possible to write structure in this code

Looks like you are on the right track.
And you are over my head with all that C stuff, but I'm sure that what you want to do is possible.

Anyway thanks your reply........i dont know its possible or not........ok thanks da
