To avoid confusion and possible irrelevant responses, please say which
of the following options best matches your requirement:

(a) your Python script is capable of being run from the command line,
and "returns" an integer value by calling sys.exit(that_value) -- you
wish to execute the script from a C program [the same way you would
execute a shell script / awk script / ...] and pick up the return value
[which may be limited by the OS to range(0, 128)]

(b) your script is a module, containing a function that returns an
integer. You wish to create an embedded Python interpreter, import
yourmodule, call yourmodule.yourfunc, convert the returned Python int
to a C int, and use it.

(c) none of the above

Cheers,
John
