Hi, I am developing an application where I have Python embedded in C
functions using the C/Python API to execute commands. My question stems
from my need to preserve a PyObject to pass between these Python
embedded C functions. My question is: do I have to call Py_Finalize() at
the end of each Python embedded C function?

The abstract structure of my code looks like this:

PyObject *po;

main() {
po = py_function_1();

// some C code in the middle here...

po = py_function_2(po);

// some more C code here...

In my implementation of py_function_1 and py_function_2 do I have to
call Py_Initialize() and Py_Finalize at the beginning and end of each of
the two functions? Or can I just call Py_Initialize at the beginning of
py_function_1 and then call Py_Finalize() at the end of py_function_2?

Thank You.

    As far I understand you only need to call Py_Initialize() and
    Py_Finalize() once per every embedded interpreter, not for an every

    Programmers don't die, they just GOSUB without RETURN.
