Those are not functions, those are keywords.

the builtin functions are in the module "__builtins__" anyway.

print can be substituted by either using printf/puts directly
or a call to pythons sys.stdout.write.

and for exec:

int PyRun_SimpleString (char *command)

or

PyObject* PyRun_String(char *str, int start,
      PyObject *globals,PyObject *locals)

could do the job
