How to look for a value in a hash?

I have a hash like

%has  = ('TCA' =>'S', 'TTC'=>'N'....)

and a 

$string = 'TCA'

I want to look for my $string in the %has and if it exist, print the value using perl like this: 

TCA, S

How can I do that? Thank you so much!

Check if the value exists.

if (exists $has{$string}) {
     printf "%s, %s\n", $string, $has{$string};
}

Keep in mind that this is case sensitive.

You should probably read up on the various Perl functions in perldoc perlfunc
