This is trickier than you might think.  Many shutdowns cannot be blocked.  For 
example, if battery power is critically low, you're going down, like it or not. 
 Further, if someone has their laptop set to hibernate when the close the lid, 
they're going to be really pissed off if your application blocks that and the 
battery expires.

On Vista and beyond, you can use ShutdownBlockReasonCreate to say "the system 
should not be shutdown for a while".

Anything that can be done in C# can be done in Python.  Do you have a C# 
example you want to copy?

Is this code not sufficient for your needs?
