Im trying to write a statement: if users input = a key in %hash print the value of the key. This code doesnt work but shows something like: 
%hash = (one => 'uno', two => 'dos', three => 'tres');

$input = <STDIN>;
chomp $input;

if ($input = (keys %hash))
{
print the value that matches the key of %hash;
}

So, if I type one at the prompt it should return with uno.
