A shorter way to create loops in Perl is
The loops can also be created by using the keys function.
Your script can also be implemented through arrays, as you are doing numerical indexing which is faster than associative indexing.
Manav
%aminoacids = ( 1 => 'Tyrosine', 2 => 'Glycine', 3 => 'Leucine', ); for $i (1..3) { for $j (1..3) { for $k (1..3) { # another test print command #print "$i $j $k\n"; # want to print out for example tyrosine tyrosine leucine if $ +i = 1, $j = 1 and $k = 3 local $"=' ' ; print "@aminoacids{$i,$j,$k}\n" ; } } }

can and should be changed tofor $i (1..3) {
and so on for other loops. This is the preferred way of looping through all keys in the hashes.for $i (keys %aminoacids) {
