Calling python function from C and import questions

[sndive@gmail.com]

Is there a better way to make a call from C than

PyRun_SimpleStr ing("import
foo_in_python\n foo_in_python.b ar(whatever)\n" );

?

I already imported the foo_in_python using PyImport_Import Module
and wonder why do I need to keep importing it every time I'm
calling a python function in that module.

I stepped thru PyImport_Import Module and it seems rather expensive.

I assume the module will end up in cache after PyImport_Import Module
so that subsequent
PyRun_SimpleStr ing("import foo_in_python\n ...
is cheaper but I still have to wonder if I what I'm doing is the right
thing or there is a much simpler way of doing this.

Does anyone know why does the import tries to load .py files before
..pyc?
Thank you.

Sure. Use the reference to the module that you got from
PyImport_Import Module; you call a method using PyObject_CallMe thod or
similar.

It has to be sure that the .pyc is up-to-date; the .pyc contains a magic
number and the modification time of the corresponding .py
