IPC via files, sockets, and shared memory are all readily available in
python.
the simplest way is to have the script write its pid to a certain file.
pidfn = '/tmp/hellowerld_ipc_pid'
if os.path.isfile(pidfn):
f = file(pidfn)
pid = f.read()
f.close()
if pid in os.popen('ps -A -o pid').read():
print "another instance of me is running!"
else:
f = file(pidfn, 'w')
f.write(str(os.getpid()))
f.close()
