Run a program and capture its output

Question

I have a Perl script that runs a python script but i need to pass information back to the Perl script. Anyone can help me to achieve this?

This is my code so far

open(my $py, "|-", "python2 /home/pi/myRead.py") or die "Cannot run Python script: $!";
while (<$py>) {
    $newCard = $py;
}
close($py);

Answer 1

my $newCard = `python2 /home/pi/myRead.py`;
