Re^3: How to create hash out of an array elements?

Then $symbolsizes[0] doesn't contains function. Perhaps it contains a trailing newline that you didn't remove using chomp?

And to see exactly what your hash does contain, use Data::Dumper (or one of its descendants). (I'm passing Dumper a reference to the hash because it prints it in a more hash-like manner that way.) `abaugher@Aliantha ~$ cat doit #!/usr/bin/perl use Modern::Perl; my @array = ( 'key', 'value' ); my %hash = @array; say "The value of 'key' is '$hash{key}'"; use Data::Dumper; print Dumper \%hash; abaugher@Aliantha ~$ perl doit The value of 'key' is 'value' $VAR1 = { 'key' => 'value' };` [download] Aaron B.

abaugher@Aliantha ~$ cat doit
#!/usr/bin/perl
use Modern::Perl;

my @array = ( 'key', 'value' );
my %hash = @array;

say "The value of 'key' is '$hash{key}'";

use Data::Dumper;
print Dumper \%hash;

abaugher@Aliantha ~$ perl doit
The value of 'key' is 'value'
$VAR1 = {
          'key' => 'value'
        };
