in thread number array with space

Or a more Perlish way of using indexes (works only in a fairly recent version of Perl):
use Modern::Perl;

my @array = qw/een twee drie vier vijf zes zeven/;

for my $index (keys @array) {
    say "$index: $array[$index]";
}

      Hey

      one more question that how to check whether the element in an array is a number or not . is there any function in perl

[reply]

        See Scalar::Util, and its function "looks_like_number". The module is core, meaning it ships with Perl.

        See looks_like_number in Scalar::Util like thus: 

        use Scalar::Util qw(looks_like_number);

 for(qw(1 perl 25 monks)){
   looks_like_number $_ ? print $_," is a Number",$/ 
                        : print $_," is not a Number",$/;
 }
