how to run a python web application from within a perl script

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.` [download] Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

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?	[reply]

op, how do those programs read data? From a file? That sounds like a great idea	[reply]
