keypress event activates before keying and only once

I'm a newbie to javascript and just wrote a script which looks for keypress event and show the code . 

<!DOCTYPE html>
<html>
    <head>
        <script>
            window.addEventListener("keypress",func(Event));
            function func(event){
                var x = event.keyCode ;
                alert("You have pressed : " + x );
            }
        </script>
    </head>
    <body>Key Press Demo</body>
</html>

The function however is being called during window load and shows undefined and it is not working continously. Let me know where I'm going wrong.

The second parameter for addEventListener expects a reference to a callback function for the event, instead you are directly calling the function which is why it executes right away. Instead just pass func

window.addEventListener("keypress", func);
