Re^2: arranging the csv file

Hi Loops,
Nice concept of solution, but you are "throwing" away the return values of the map function, so really, I wouldn't build my hash data like this. Moreover, this method is throwing a warnings Argument "\n" isn't numeric in addition ...
I would rather do like so:

use strict;
use warnings;

my %data;
while(<DATA>){
  my ($key,$value) = split/\s+|,/=>$_,2;
  $data{$key} = $value;
}
print $_,',',$data{0+$_},$/ for qw( 10.1 100.1 25.1 103.1 );


__DATA__
100.1,A ,25, 36,56,89,45,36,56
25.1 ,B,232,565,65,56,56,48,25
103.1,C,25,5,6,9,4,5,56,889,9
10.1,D,5,6,5,8,9,8,12,23,36,6

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

Marrying your and Loops' approach: `use strict; use warnings; my %data = map { /(.?)\s,/ => $_ } <DATA>; print @data{ qw( 10.1 100.1 25.1 103.1 ) }; __DATA__ 100.1,A ,25, 36,56,89,45,36,56 25.1 ,B,232,565,65,56,56,48,25 103.1,C,25,5,6,9,4,5,56,889,9 10.1,D,5,6,5,8,9,8,12,23,36,6` [download] Question: can anyone do this as a oneliner without a named hash?

Actually, I was not able to do it, and I have been experimenting with various types of sigils and parentheses for a while. Many thanks!	[reply] [d/l]
