Test if Script Already Running

I have a number of simple scripts I run with cron hourly on Centos
linux. I want the script to check first thing if its already running
and if so exit.
In perl I did it with this at the start of every script:
use Fcntl ':flock';
open LH, $0 or die "Can't open $0 for locking!\nError: $!\n";
flock LH, LOCK_EX | LOCK_NB or die "$0 is already running somewhere!\n";
How can I do something like this in Python?
