#include 
#include 

int main () {
  Py_Initialize();
  PyRun_SimpleString("var1 = 1");
  PyRun_SimpleString("var2 = ['bla', 'blalba']");
  PyRun_SimpleString("var3 = {'3' : 'Three', '2' : 'Two', '1' : 'One', '0' : 'Ignition!'}");
  PyRun_SimpleString("print('end of file - tryStuff!!')");

  PyObject *mainModule = PyImport_AddModule("__main__");
  PyObject *var1Py = PyObject_GetAttrString(mainModule, "var1");
  int c_var1 = PyLong_AsLong(var1Py);
  printf("var1 with C: %d\n", c_var1);

  Py_Finalize();
  return 0;
}
