'for' loop in embedded Python

[Randy Heiland]

I'm simply wondering if I can use a 'for' loop in an embedded Python pgm
via PyRun_SimpleString, as in the following example pgm.  In general,
how does it know about indentation/end of loop?

#include "Python.h"

#include <import.h>
#include <graminit.h>
#include <pythonrun.h>

main(int argc, char **argv)
{
 Py_Initialize();

 printf("Hello, brave new world\n\n");

 /* Execute some Python statements (in module __main__) */

 PyRun_SimpleString("idx=0\n");
 PyRun_SimpleString("s=0\n");
        printf("--- did s=0\n");
 PyRun_SimpleString("print range(3)");
        printf("--- did print range(3)\n");
 PyRun_SimpleString("for idx in range(5):\n");
        printf("--- did for\n");
 PyRun_SimpleString("s=s+idx\n");
        printf("--- did sum\n");
 PyRun_SimpleString("\n");
 PyRun_SimpleString("print s\n");
        printf("did print s\n");

 /* Some more application specific code */
 printf("\nGoodbye, cruel world\n");

 /* Exit, cleaning up the interpreter */
 Py_Exit(0);
}
---------------------------------
I get a  SyntaxError :
Hello, brave new world

--- did s=0
[0, 1, 2]
--- did print range(3)
  File "<string>", line 1
    for idx in range(5):
                                 ^
SyntaxError: unexpected EOF while parsing
