I'm trying to make a simple webpage which executes a seperate python script located in my home directory. There is nothing to be printed on the webpage since the script consists of commands to launch weather forecast and news reporting via the raspberry pi's speakers.
I searched high and low but could only find method to print system information on the page. If possible i wish to add a single button to the webpage (index.php) which when pressed will activate the script shown below. Thanks!

21 January 2015:
Tried creating index.php with code
<html>
<body>
<a href="runscript.php">Run script.</a>
</body>
</html>
and runscript.php with
<html>
<body>
Starting script.
<?php
shell_exec('touch /tmp/foo.txt');
?>
</body>
</html>
result: foo.txt was successfully created in /tmp folder.
However when I tried changing the command to sudo python /home/pi/alarm.py the script was not executed. I also tried changing index.php to
<form action="alarm.py">
<input type = "submit" value = "submit" name ="load">
</form>
but webpage shows an internal server error when button(submit) was pressed.
