Hi Paul, first of all thanks for the help.
I am aware of the first solutions, just now I would like to experiment a bit
with using named pipes (I also know that the example is trivial, but it just
to grasp the main concepts)

Your second example doesn't work for me.. if named_file is not a file in the
folder I get an error saying that there is not such a file.
If I create named_pipe as a named pipe using os.mkfifo("named_file",0777) than
the code hangs.. I think it is because there is not process that reads the
content of the pipe, so the system waits for the pipe to be emptied.
Thanks a lot in advance for the help in any case.
Luca
