The problem is that you're not passing the data at all. You never
interpolate the pid_data value into the string(s) constituting your
embedded JavaScript (though you did do it just fine in the pure HTML).
The Python variable `pid_data` is not somehow magically accessible to
JavaScript; you must explicitly insert its value somewhere.

Change that line to:
<body onload="showPID("""+pid_data+""")">
As an example, if the PID happens to be 42, then the outputted
fragment will end up being:
<body onload="showPID(42)">
As a sidenote, I would recommend using something higher-level than the
`cgi` module. Python has an abundance of web frameworks and templating
languages; take your pick.
