Re: getting arguments computed by a swi program from a bash shell

Thanks for your answer and that of Kilian.

In fact, my swi prolog program is already a script that I call
from a python script (and not a shell script as I have previoulsy told).

I (naively) thought that there was a way to a swi-prolog script
to return values to the program which called it (here my python script),
as a function return values (possibly just one)
to the function which called it.
