 There's... no Python code in that. Why not simply
 open(/proc/acpi/button/lid/LID/state) and read from it, instead of
 using cat and awk?

The correct way to implement this is to use the power management
services available on the System D-Bus.

Integrating with D-Bus from Python is easy!

 The script returns either open or close instead of printing the whole
 file contents. I thought some people would find it useful (^_^;).

Not having a Linux laptop handy I can't test it, but my point is that
text parsing of that nature can be done directly by Python. You can
snip out the open or close easily with one, maybe two lines of
code at the most, and that without dropping to a shell, a completely
superfluous 'cat' process, and awk. You then capture the STDOUT of
that and promptly print it to your own STDOUT. Why not either do it
truly in Python, or do it directly in a shell script and skip the
Python interpreter?

Or for that matter, why not just make it a bash script instead of Python?
It's kind of pointless to go to all the trouble of starting a Python
interpreter just to have it start a subprocess.
