BhariD has asked for the wisdom of the Perl Monks concerning the following question:

I have a perl script which I am using to generate some data. I want to process this data (as an input) through a program that is written using the Webware for Python Web application framework and the Rialto client-side Javascript widget library, to generate the results.

Does anyone know how I can call or run this program from within my perl script. I would appreciate any kind of help or pointers.

Thanks

    Use a piped open to feed the data to the python script: 

    my @data = genData();

my $pid = open OUT, '-|', 'python theScript.py' or die;

print OUT $_ for @data;

close OUT;

waitpid $pid, 0;
## The python script has finished.

      You sort of forgot about the data, didn't you? The op said they were trying to send some data to a python program.

      op, how do those programs read data? From a file?

        That sounds like a great idea
