perl - Print hash of arrays with commas between the elements of the array -


i using

  $fields ( sort {$a<=>$b} keys %hoa) {        print "$fields-->@{$hoa{$fields}}\n";    }

to print hash. output is:

0-->2132123 321321321 abcdefg 32 def ...

i like: 

0-->2132123,321321321,abcdefg,32,def,...

is there way alter print statement give me commas? rather not use s/ /,/.

use explicit join.

for $fields ( sort {$a<=>$b} keys %hoa) {     print "$fields-->" . join (',', @{$hoa{$fields}}) . "\n"; }

or localize version of $list_separator per perlvar

for $fields ( sort {$a<=>$b} keys %hoa) {     local $" = ',';     print "$fields-->@{$hoa{$fields}}\n"; }
