Hi there. I have always been somewhat confused my hashes in perl and today I've found myself in need of using one. As you can see, I've gotten so far with it, but could someone please advise as to how to print out the 'value' for any given 'key'. So, for example, I wish to use the hash table to look up '1' and print out 'tyrosine'. Thanks. Any help much appreciated.

%aminoacids = (

           1 => 'Tyrosine',
           2 => 'Glycine',
           3 => 'Leucine',

           );
for($i = 1; $i<4; $i++)
{
    for($j = 1; $j<4; $j++)
    {
    for($k = 1; $k<4; $k++)
    {
        # another test print command
        #print "$i $j $k\n";

        # want to print out for example tyrosine tyrosine leucine if $
+i = 1, $j = 1 and $k = 3

    }

    }

}

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
