Error : python.h : no such file or directory

I think this should be "Python.h" not "python.h"

Make this do something, or you'll have an unresolved external. e.g.:

PyObject* getres(PyObject* self, PyObject* args)
{
	printf("Hello world\n");
}

This may need to be: { NULL, NULL }

> {

That bit seems okay.

> int getresult

>     printf("enter 2 numbers\n");
>     scanf("%d %d", &x,&y);

Hmm. This is a bit dodgy.

Not really a Python problem. More a compiler related one. The solution
depend on what compiler you are using.

Assuming you are on Win32, and installed Python from the installer do:

cl -Ic:/progra~1/python/include -c resmodule.c		-> resmodule.obj

If you're on a Unix/Linux box:

cc -I/usr/local/include/python1.5 -c resmodule.c	-> resmodule.o

You'll also need to link with python15.lib/libpython1.5.a.
