20 Minutes: Text to data: hashes I

Hashes are a special kind of array indexed by a string, rather than by a number:


    $attributes{color}    = 'blue';
    $attributes{speed}    = 100;
    $attributes{spin}     = 'negative';
    $attributes{altitude} = 7500;
    
    print "Spin is: ", $attributes{spin}, "\n";

Assign a bunch of values to a hash by supplying a list of key/value pairs:


    %attributes = (color    => 'blue',
                   speed    => 100,
                   spin     => 'negative',
                   altitude => 7500);
