pmfind will find all installed modules, whether they're in use or not.

Hello,
We have one software which is installed at one machine. The software was
developed by many developers(students) as it was used in multiple projects
in the lab, all the code is written in perl. Now we want to do the backup of
that software for that we want to make one copy running on a new m

Wouldn't know, don't do Python.
Perl's both hash and array use ().
But anonymous hash and array use {} and [].
Hashes use {}, arrays use [], lists use ().
When you set an element of a hash, you use {} to surround its key:
$hash{$key} = $value;

sure.
first I will use unix's ls command like ls -ltr.
in perl one of the ways:
my @sorted = map { $_->[0] }
sort { $a->[1] <=> $b->[1]
print join "\n", sort {(stat $a)[8] <=> (stat $b)[8]} glob "./*";

Yes,its much more powerful, the way you said, but in my case it won't be
