Printing an Hash

anshumangoyal has asked for the wisdom of the Perl Monks concerning the following question:

I have a hash which has around 20 Key Value Pairs. I want to print these values in a file and on screen in such a way that the indentation is not lost. I want to print it in mysql query output format. The Keys will be name of parameter and below it the value of the key has to be printed. I tried with sprintf but it's not a success. The keys length are different and so it he value length. What is the best possible solution?

    Why don't you type up an example of how you want the data to look, that'd help a lot in pointing you to a solution.

    This should keep all of your indentation, though Im not aware of how you want it printed out, so I just put each key and value on a newline

    use v5.14; my %hash = (' key' => 'value ',"\tkey2" => "value2\t"); open(FILE,'>>','filename') or die "$!"; while ( my($key, $value ) = each(%hash)){ print "$key\n$value\n"; print FILE "$key\n$value\n"; } close FILE;

      or Data::Printer (my fave because you have to type less, you get fancy colors, and indices are included in the output)

    printf "%s\n", join("\n",map { $_ . " " . $hash{$_} } sort keys %hash);
