Not really sure why I would ever want to do this but here is how to run python code from within C Code. Here is a test program that prints a string using python being called from C.
/*
* Test program to run python code from C
* Compile with gcc -Wall -I /usr/include/python2.7/ -lpython2.7 -o runpython runpython.c
*
*/
#include <Python.h>
int main() {
Py_Initialize();
PyRun_SimpleString("print('print using python')");
return 0;
}
